Look in the CCS Code Library forum. It has links to a 4x4 keypad driver. |

All you need to do is look at the program that PCMprogrammer offered above. It is well commented and easy to understand, very easy to modify to a 4 x 3 keypad.
Refer to the onscreen help(F11) that CCS supplies to read what the commands/functions/etc. are doing if you're not sure. |

CCS Code Library already has the 4x3 driver. You don't have to modify
the 4x4. Here's the link:
http://www.ccsinfo.com/forum/viewtopic.php?t=26333
Also, CCS has their kbd.c driver, which is for a 4x3 keypad:
