<sect>Overview<p>
|
||||||
|
|
||||||
|
This file contains an overview of the Atari 5200 runtime system as it comes
|
||||||
|
with the cc65 C compiler. It describes the memory layout, Atari 5200 specific header
|
||||||
|
files, available drivers, and any pitfalls specific to that platform.
|
||||||
|
|
||||||
|
Please note that Atari 5200 specific functions are just mentioned here, they are
|
||||||
|
described in detail in the separate <url url="funcref.html" name="function
|
||||||
|
reference">. Even functions marked as "platform dependent" may be available on
|
||||||
|
more than one platform. Please see the function reference for more
|
||||||
|
information.
|
||||||
|
|
||||||
|
|
||||||
|
<sect>Binary format<p>
|
||||||
|
|
||||||
|
The standard binary output format generated by the linker for the Atari 5200 target
|
||||||
|
is a cartridge image. It is of course
|
||||||
|
possible to change this behaviour by using a modified startup file and linker
|
||||||
|
config.
|
||||||
|

<sect>Memory layout<p>
|
||||||
|
|
||||||
|
cc65 generated programs with the default setup use the RAM space from $021C to
|
||||||
|
$3FFF. If you want to reserve memory for the display list and screen buffer
|
||||||
|
you should define the __RESERVED_MEMORY__ linker variable. The number
|
||||||
|
of bytes specified by __RESERVED_MEMORY__ are lowering the top of
|
||||||
|
memory, therefore the available
|
||||||
|
RAM memory for the program is $021C to $3FFF-__RESERVED_MEMORY__.
|
||||||
|
The default linker config file sets __RESERVED_MEMORY__ to $1E0
|
||||||
|
to reserve space for an optional CONIO text screen.
|
||||||
|
|
||||||
|
Special locations:
|
||||||
|
|
||||||
|
<descrip>
|
||||||
|
<tag/Text screen/
|
||||||
|
The text screen is only enabled if any of the CONIO output functions
|
||||||
|
is used in the program. Its size is 20x24 characters (Antic mode 6,
|
||||||
|
BASIC mode 1). The text screen is located at $3E00. The
|
||||||
|
address of the screen memory is available at runtime in the variable
|
||||||
|
SAVMSC ($001B).<p>
|
||||||
|
If the program doesn't use any CONIO output functions it needs to setup its own
|
||||||
|
display list.
|
||||||
|
|
||||||
|
<tag/Stack/
|
||||||
|
The C runtime stack is located at $3FFF-__RESERVED_MEMORY__ and growing downwards.
|
||||||
|
|
||||||
|
<tag/Heap/
|
||||||
|
The C heap is located at the end of the program and grows towards the C
|
||||||
|
runtime stack.

The following pseudo variables declared in the <tt/atari5200.h/ header
|
||||||
|
file do allow access to hardware located in the address space. Some
|
||||||
|
variables are structures, accessing the struct fields will access the
|

|
chip registers.

<descrip>

The <tt/GTIA_READ/ structure allows read access to the GTIA. The
|
||||||
|
<tt/GTIA_WRITE/ structure allows write access to the GTIA.
|
||||||
|
See the <tt/_gtia.h/ header file located in the include directory
|
||||||
|
for the declaration of the structure.
|
||||||
|
|
||||||
|
<tag><tt/POKEY_READ/ and <tt/POKEY_WRITE/</tag>
|
||||||
|
The <tt/POKEY_READ/ structure allows read access to the POKEY. The
|
||||||
|
<tt/POKEY_WRITE/ structure allows write access to the POKEY.
|
||||||
|
See the <tt/_pokey.h/ header file located in the include directory
|

|
for the declaration of the structure.
|
||||||
|
|

<tag><tt/ANTIC/</tag>

The <tt/ANTIC/ structure allows read access to the ANTIC.
|
