Project Source Files
--------------------
To build the ACPRD firmware, add the following source files to a compiler project:

acprd_main.c
acprd_timer.c
acprd_encoder.c
acprd_keyb.c
acprd_freqout.c
acprd_song.c
acprd_vectors.c
s12co_spiio.c
s12_atd.c
s12_crg.c
s12_eets.c
s12_sci.c
s12_spi.c
t6963.c
display.c
timedate.c

Linker Settings
---------------
The linker options could be set as follows (example):

- text (code) segment start at 0x4000 (start of Flash EE)
- data (bss)  segment start at 0x1000 (start of RAM)
- stack pointer set to 0x4000 (end of RAM)

Compiler Dependencies
---------------------
The source code is ANSI-C compliant with the exception of using // for comments.
Some compiler specific issues are covered in the header file DATATYPES.H.
The project was implemented using ImageCraft's ICC12 compiler and tested under
Metrowerks CodeWarrior, though it should be possible to build the project with
any other HC(S)12 compiler as well.

The C-startup code is start12.c for CodeWarrior and the default crt12.c for the
ImageCraft Compiler. When compiling the project with Codewarrior, set the
compiler option "-TuC" in order to make "char" variables unsigned by default.
