+<title>Atari 5200 specific information for cc65
+<author>
+<url url="mailto:chris@groessler.org" name="Christian Groessler"><newline>
+<date>2014-05-27
+
+<abstract>
+An overview over the Atari 5200 runtime system as it is implemented for the
+cc65 C compiler.
+</abstract>
+
+<!-- Table of contents -->
+<toc>
+
+<!-- Begin the document -->
+
+<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.
+
+</descrip><p>
+
+
+
+<sect>Platform specific header files<p>
+
+Programs containing Atari 5200 specific code may use the <tt/atari5200.h/ header file.
+
+
+<sect1>Atari 5200 specific functions<p>
+
+<itemize>
+<item>TBD.
+</itemize>
+
+
+
+<sect1>Hardware access<p>
+
+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>
+
+ <tag><tt/GTIA_READ/ and <tt/GTIA_WRITE/</tag>
+ 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.
+ See the <tt/_antic.h/ header file located in the include directory
+ for the declaration of the structure.
+
+</descrip><p>
+
+
+<sect>Loadable drivers<p>
+
+All drivers must be statically linked because no disk I/O is available.
+The names in the parentheses denote the symbols to be used for static linking of the drivers.
+
+
+<sect1>Graphics drivers<p>
+
+No graphics drivers are currently available for the Atari 5200.
+
+
+<sect1>Extended memory drivers<p>
+
+No extended memory drivers are available for the Atari 5200.
+
+
+<sect1>Joystick drivers<p>
+
+<descrip>
+
+ <tag><tt/atr5200std.joy (atr5200std_joy)/</tag>
+ A joystick driver for the standard Atari 5200 joystick is
+ available. Depending on the version of the 5200 console, two or four joysticks can be attached.
+
+</descrip><p>
+
+
+<sect1>Mouse drivers<p>
+
+No mouse drivers are available for the Atari 5200.
+
+
+<sect1>RS232 device drivers<p>
+
+No serial drivers are available for the Atari 5200.
+
+
+
+<sect>Limitations<p>
+
+<sect1>Disk I/O<p>
+
+Disk I/O is not supported by the <tt/atari5200/ target. This means that
+you cannot use any of the following functions (and a few others):
+
+<itemize>
+<item>fclose
+<item>fopen
+<item>fread
+<item>fprintf
+<item>fputc
+<item>fscanf
+<item>fwrite
+<item>...
+</itemize>
