* Mode 2 - Bi-Directional Bus **NOT USED BY CPC** In some of these modes port
C is used as a control/status port for port A or B. It can be used to confirm
when data transfer may take place, and reflect any other flags. The 8255 PPI is
therefore supplied with the added option for the user to set or reset any indi
vidual bits in port C. The I/O status, mode of operation and bit setting is de
fineKERNAL TXTKERNAL TXTdKEYMAP TXT)£KM TXTKDISC d by the 8255 PP
I control byte. (The control byte is accessed using port &F7xx.(8255 Control po
rt)) The ports may be accessed separately by the CPU. Port A is accessed using
port &F4xx. Port B is accessed using port &F5xx. Port C is accessed using port
&F6xx. NOTE Mode 0 operation Mode 0 operation does not require other ports t
o be used to control data transfer. Data may only be sent to a port if the port
is defined as output, and data may only be read from a port when the port is s
et to input. Using the 8255 Ports -------------------- When writing to a po
rt 1) Make suretheport is operating as output. (This is done by sending a c
ontrol byte to port &F7xx). 2) Write the data to the port. 3) Return the port to
it's original I/O Status. When reading from a port 1) Make sure the port is o
perating as input. (This is done by sending a control byte to port &F7xx). 2
) Read the data from the port. 3) Return the port to it's original I/O Status.
8255 PPI Control Byte --------------------- This byte controls the Input/Outp
ut (I/O) status and operating mode of each port. It also has a secondary funct
ion which allows the user to set or reset a particular bit of port C. To send
a control byte to the 8255, simply sent the byte to port &F7xx. (NOTE The contr
ol byte can only be written, it cannot be read.) The f8255 Parallel Peripheral
Interface ---------------------------------- The 8255 is a general purpose inp
ut output chip. It is connected to the PSG, keyboard and cassette recorder. Pr
ogramming the 8255 -------------------- The 8255 has 3 8-bit ports (A,B and C),
each of which can have a different I/O Status (i.e. input or output). Port C c
an also be programmed to operate in two halves. (As two separate 4-bit ports).
There are 3 basic modes of operation under which the ports Nunction to be ex
ecuted by the 8255 is dependant on the state of bit 7. If bit 7 is 1, the rema
ining bits are used to define the I/O status, and operating mode of each port.
If bit 7 is 0, the remaining bits are used to determine what bit is set (set
to 1) or reset (set to 0) of port C. Configuration control byte -------------
------------- When bit 7 is set to 1, the command byte operates in the followin
g way Bit 7e may crash. (The firmware expects the operating modes to be the s

nfiguration functio Using the 8255 Ports -------------------- When writing to
a port 1) Make sure the port is operating as output. (This is done by sending
a control byte to port &F7xx). 2) Write the data to the port. 3) Return the po
rt to it's original I/O Status. When reading from a port 1) Make sure the port
is operating as input. (This is done by sending a control byte to port &F7x
x). 2) Read the data from the port. 3) Return the port to it's original I/O Stat
us. 8255 PPI Control Byte --------------------- This byte controls the Input
/Output (I/O) status and operating mode of each port. It also has a secondary f
unction which allows the user to set or reset a particular bit of port C. To se
nd a control byte to the 8255, simply sent the byte to port &F7xx. (NOTE T
he control byte can only be written, it cannot be read.) The function to

I understand them fully and, I can explain exactly what they do. Programming
the CRTC -------------------- The CRTC has 18 registers (0-17) which are used
to control the screen, screen cursor, and to sense a light pen/gun. To access t
hese registers, the CRTC has 3 control ports. One port to select a register, o

--------- A register is selected by sending the register number (in the range
0-17) to port &BCxx. This register will remain selected until another is selec
ted. This means you can write to the same register many times, without having to
re-select the register each time. (See t X X *15 R/W C

rs may vary during normal operation. NOTE Experimenting with the registers c

ramming example) Writing to a register --------------------- Once a registe
r has been selected using the method above, the user can write data into it. Dat
a can be written into the register by sending the data to port &BDxx. If the
selected register cannot be written to, there will be no effect. (See th
e programming example) Reading a register Just switch the computer off and
then on, and everything will be ok again. Register usage -------------- Certa
in registers can be used for various things. Here is a list of registers and the
ir common usage. Register 0 Horizontal splitting (changing of screen addre

hen ------------------ Once a register has been selected, it can be read fr
om. The data in the register can be read from port &BFxx. If the register canno
t be read, a value of &FF will be returned. (See the programming example) NOTE

h of the screen may be increased or decreased, to get the desired screen width
. If the value programmed is increased, the width of the screen will increa

Therefore, using this register and register 2, it is possible to position

&8000-&C000 1 1 &C000-&FFFF In this way, the screen can be po
sitioned almost anywhere in memory. The screen address is only changed when
a VSYNC occurs. So, if you attempt to change the screen address, as the electr
on beam is drawing the screen, only one screen Register 5 - Vertical total adj
ust ----------------------------------- This register allows the vertical p
osition of the screen to be positioned to any pixel offset from the cur
rent vertical position defined in register 7. If the value is increased, the
picture will shift down by a pixel line, if it is decreased the picture will
shift up by one pixel line. This register used in conjunction with register 12
and 13, can be used to get perfect pixel by pixe will be shown. (To change the
screen address more than once a special technic called "rupture" or "hardware s
plitting" is needed. This special effect was developed by The Logon System dem
o team.) The CRTC cannot access the extra memory, so it will only display
screens which are located in memory blocks 0-3 only, regardless of any ram conf
iguration. (i.e. it will only display screens in the first bank of 64k). I
f you change the ram configuration, so that a different 16k block is
l vertical scrolling. (see programming example) Register 6 - Vertical displ
ayed -------------------------------- This register defines the height of th
e screen in character sized units. If the value programmed is increased, th
e height of the screen will increase, if the value programmed is decreased,
the height of the screen will decrease. The normal value programmed is 25. Th
e height of the monitor screen is 35 charaswitched into the area which hold
s the screen there will be no effect on the picture. (see the document on the
Gate Array for more information). Bit 3 and 2 determine how much memory the CRT
C can use for the screen. The CRTC is capable of displaying 16k or 32k screens.
Bits 3 and 2 are defined in the following way Bit 3 Bit 2 Screen memory ---
-------------------------- 0 0 16k 1 0 16k 0 1
16k 1 1 32k When the CRTC is accessing 32k, you can expancters.
NOTE We can find the height of the screen in pixel lines, by multiplying th
is by the value in register 9 plus 1. Height of screen register 6 value*(regis
ter 9 value+1) Register 7 - Vertical sync position -------------------------
----------- This register defines the vertical position of the screen within
the monitor screen. If the programmed value is increased, the screen will shi
ft upwards, if the programmed val Nd the screen size so that you can have a pic
ture which covers the borders! (overscan) When 32k is selected, the first
and second screens occupy the following range of addressess First screen

7FFF &8000-&BFFF &8000-&BFFF &C000-&FFFF &C000-&FFFF &0000-&3FFF (s
ee the programming example) Bit 1 and 0 are used with register 13 to do
hardware scrolling. Register 13 contains the lower 8 bits of the Overscan, O
verscan is the effect where the screen is expanded to fill the whole monitor sc
reen, So there are no borders remaining. It is a simple effect to use, but
working out screen addressess becomes more difficult. (especially where the
first screen ends and the second screen starts). To expand the screen, we us
e registers 1, 6, 2 and 7. Register 1 is used to set the width of the scr
een, register 6 the height of the screen, register 2 the horizontal position of
the sc offset and bit 1 and 0 contain the upper 2 bits of the offset. The
offset is 10 bits and defines the position of the screen within the 16k block
specified in bits 5 and 4. So, by changing the value contained in register 13
, and bits 1 and 0 of register 12, the screen can be scrolled. This effect
is called hardware scrolling. (see programming example) Summary Bit 7 Not used
. Bit 6 Not used. Bit 5 Memory block of start of screen Bit 4 Bit 3 Screen
memory Bit 2 Bit 1 Offsreen and register 7, the vertical position of the scre
en. When this is done, we can see that parts of the screen repeat. To over
come this, we tell the CRTC to use 32k instead of 16k. NOTE On some CRTC t
ypes, the screen width must not exceed 48 characters otherwise it
will not work. So to maintain compatibility keep the width of the
screen below 48. (Aplies to CRTC type 2). The code for overscan is. **

ect works by changing the start address of the screen. (There is no shifting or
moving of data). By doing this we can make it look like the screen is scrolling
. It is important to note, that only a 16k screen can be fully scrolled. If a 3
2k screen is scrolled too much, it splits into a 16k screen which repeats.
The screen is scrolled in character sized chunks. This produces very fast sm
ooth hardware scrolling. However it is often too fast. Therefore, it is

INK IT WAS LONGSHOT WHO FOUND IT, OR FRED CRAZY. ALL CREDITS TO THEM. I HOPE THE
Y DO NOT MIND ME GIVING AWAY A FEW SECRETS. This technic is used widely in demo
s. Normally the screen address can only be changed once. The CRTC only allows th
e screen address to be changed when a VSYNC occurs, i.e. when the beam has finis
hed drawing the screen and moves back to the top-left again, so that it can star
t again. This technic l cases we must ensure the offset remains in the rang

change the screen address anywhere on the screen. This allows you to do amazin
g things. e.g. the top part of the screen scrolling (using hardware), whilst th
e lower part is stationary. (As seen in Super Cauldron and Prehistorik II). Bot
h of the sections of the screen can start at a different memory location. So th

detection in it - like VOYAGE 93 by BENG!). Also, you can achieve overscan by u
sing this technic. To set-up the split is easy enough. a) First the interrupt
vector must be set so that it does nothing. b) Then every frame-flyback/VYSNC, p

The interrupts effectively split the screen into 6 blocks. So we can easily wai
t for an interrupt to occur by using a HALT instruction, then we can program the
split values. (This code can be found in the file SPLTSHLL.MAX). Since we cha
nge the interrupt vector to something different, the keyboard will not be scanne
d or anything done, so all this has to be done, by programming the hardware dire
ctly. Now to actually setup the splits, we useSelecting an Expansion Rom ------
-------------------- To select an expansion rom, simply send the number of the
expansion rom to port &DFxx. (An expansion rom may have a number from 0-255).
Where a value of 0 will select BASIC, and a value of 7 will select AMSDOS.
However this process only selects the expansion rom. It does not allow the user
to access any routines in the rom. To allow routines to be accessed the user
must enable the upper rom using the Gate Array. (See programming the gate ar re
gister &4 of CRTC. Simply program the height of the block you want (in characte
r sized units)-1. Then before the block will end, program a new block height. T
he total height of the screen is 38 characters tall. So, all the blocks heights
should add up to 38. So lets say, we want the screen split in half. We want, tw
o blocks of height 19 characters, top block using memory at &4000-&8000, the sec
ond using memory at &C000-&FFFF. the code would be ray to see how this is don
e). A programming example is given to show how to select and disable an expa
nsion rom. Note port &DFxx is a write only port, reading will return a nonsen
se value. Programming Examples a) Selecting an expansion rom -----------

ER TXT NThe Gate Array -------------- The gate array is a specially designed c
hip exclusively for use in the Amstrad CPC. It is for this reason not much is kn
own about it. It is responsible for controlling screen mode, colour palette
, ram configuration and rom configuration. The new ASIC Gate Array (in the new
Plus machines) is described in a different section. In standard mode on the Pl
us machines (that is when the new ASIC Gate Array has not been enabled), it ac
ts as a standard gate array, allowing pware pallette). The hardware colour numb
er is different to the colour range used by the firmware, so a conversion cha
rt is provided for the corresponding firmware/hardware colour values and the co
rresponding colour name. Even though there is provision for 32 colours, only
27 are possible. The remaining colours are duplicates of those already in the
colour palette. Note The firmware keeps track of the colours it is using. Ever
y VSYNC (assuming interrupts are enabled) the firmware sets the colourograms on
the CPC to work on the Plus machines without modification. However when the n
ew ASIC gate array is enabled, it allows the user to use a number of extra enhan
cements. The Gate Array is described here, as it would be on a standard CPC.
Controlling the Gate Array -------------------------- The gate array is co
ntrolled by sending values to port &7Fxx. The function which is to be perfor
med is dependant on the settingsrs. This enables the user to have flashing colo
urs. If the user selects a new colour using the gate array, the new colour will
flash temporarily and then return to it's original colour. This is due to the
firmware re- setting the colour. When using the firmware, use it's routine
s to select the colour, and the colour will remain. Summary Bit 7 Gate Array

only and cannot be read. A brief description of the functions are described
below with their settings for bit 7 and 6. Bit 7 Bit 6 Function ----------
-------------- 0 0 Select which pen is to have its colour changed.

. 1 Bit 0 Select screen mode and rom configuration -----------------------
----------------- This is a general purpose register responsible for the screen
mode and the rom configuration. Screen mode selection --------------------- T
he function of bits 1 and 0 is to define the screen mode. The settings f
or bits 1 and 0 and the corresponding screen mode are given in the table below.
From the combinations possible, we 1 1 Select ram configuration
(bank switching). Pen selection ------------- When bit 7 and bit 6 are set
to 0, the remaining bits determine which pen is to have its colour changed. Bit
s 3 to 0 define which pen is to be selected. When bit 4 is set to 1, the valu
e contained in bits 3-0 is ignored and the border is selected. The pen remains
selected until another is selected. Each mode has a fixed number of pens. Mode
0 hcan see that 4 modes can be defined, although the Amstrad only has 3. Mod
e 3 is similar to mode 0, because it has the same resolution, but it is li
mited to only 4 colours. This mode may be different on different versions of t
he Gate Array and on different CPC models. The screen mode is changed when
a HSYNC occurs. Bit 1 Bit 0 Screen mode --------------------------

s. Rom configuration selection --------------------------- (See the memory ma
p for more information) Bit 2 is used to enable or disable the lower r
om. The lower rom occupies memory addressess &0000-&3fff. When it is enabled
, reading from &0000-&3FFF will return data in the rom. When a value is writte
n to &0000-&3FFF, it will be written to the ram at the same address as the rom.
When it is disaxed' with the main ram. The CPU is capable of accessing a ma
ximum of 64K at one time. To access extra memory, blocks in the main ram (ba
nk 1) can be exchanged with blocks in the extra ram. The number of blocks exchan
ged and the the blocks they change place with changes depending on the r
am configuration used. Ram configurations ------------------ Bits 2-0 select
which ram configuration is to be used. When configuration 0 is selecte
d (regardless of the bank selected), the CPUbled, data read from &0000-&3F
FF will return the data in the ram. Similarly, bit 3 controls enabling or disab
ling of the upper rom. The upper rom resides in memory addressess &C000-&FFFF.
The upper rom can be basic or any other extra expansion roms which may be pl
ugged into an expansion board. The upper rom is selected by writing the rom num
ber to port &DFxx. (See upper rom selection for more information). When the upp
er rom is enabled, reading from &c000-&ffff, will return data in the rom. Whe
will only access the main ram. When configuration 2 is selected the CPU will
only access the bank selected. In the table above, 0-3 are the blocks in the
main ram (bank 1), and 4-7 are the blocks of the selected bank, as they wou
ld normally be arranged shown below. Their new position, is the position they
would take if that configuration was used. It is not adviseable to use confi
guration 2 when the firmware is running, or the computer will crash and you w
ill lose valuable data. NOTE Nn data is written to &c000-&FFFF, it will be
written to the ram at the same address as the rom. When the upper rom is disab
led, and data is read from &c000-&ffff the data returned will be the data in th
e ram. Bit 4 controls the CPU interrupts. A CPU interrupt occurs every 3
00th of a second. When an interrupt occurs, the CPU stops executing the curren
t program, and executes an interrupt program. When the interrupt program
has been completed, it returns to the current program. (Sormally the CPC
runs in ram configuration 0 (AMSDOS) and configuration 1 (CP/M). Normal

long but only the first 16 characters are significant. All alphabetic
characters in the name should be in upper case and the last character of
the name should have bit 7 set. The rom select and routine addresses
returned are suitable for calling KL FAR PCHL. The list of external c

The command tables are scanned i must be a background rom or the req

the rom is the current foreground rom. The foreground program should initi

given. It may chose whether to enable background ROMS or not. KL ROM WALK
may be used to initialize a particular background ROM or this routine may
be used to initialize all available background ROMS or this n the
opposite order to that in which the command servers were introduced.
Thus, RSXs will tend to take precedence over background roms, since
rsxs are in general, initialized after background roms. Background roms
are normally initialized in reverse order of rom select address, so lower
numbered roms will take precedence over higher. The first-entry in a ba
ckground roms command name table (the one associated with the power-up
entry) may be used as routine may be used to initialize particular ro
ms. This routine causes the background roms power-up initialization entry
to be called. This entry may allocate some memory for the background
roms use by adjusting the values in DE and HL before returning. Once
the ROM has been initialized the Kernal adds it to the list of
external command servers, and notes the base of the area which the ROM has

IND COMMAND may be used, therefore, to find out whether a particular backg

and greater than 15 on v1.1 firmware is found. The on-board basic ma

asynchronouse bit is set then the event is an asynchronous event, othe
rwise it is a synchronous event. Asynchronous events do not have priorities
and so the priority field is ignored. If the express event bit is set t

he count is still greater than zero then there are further events
outstanding and the event is placed back on the synchronous event
queue. The event may be disarmed between KL NEXT SYNC and KL DONE SYNC
. Setting the event count to one beforesm allows event routines to poll
for, and process, events of higher priority. The priority returned by t
his routine must be unchanged until it is passed to KL DONE SYNC/. KL NEXT
SYNC enables interupts. The procedure for processing synchronous events
is TRYAGAIN CALL KLNEXTSYNC return next event, if any JR

lling KL DONE SYNC forces multiple events to be treated as a single event
