Looking for info on HCS12 Programming...

[venz]

Does anyone have some experiance with programming Motorola's HCS12 microcontroller in C?
I'm looking for some good examples on peripheral programming.
Also external addressing on the multiplexed Data/Address bus. (A Little unclear in documentation)

Are there any libraries for peripherals available? (IAR, CW or ICC)

Thanx in advance.

HCS12

Hello,
HCS12 microcontroller is revised and improved ver. of the HC12 16 bit microcontroller.So far as I know they improved flash a lot. It needed 1min or so to programm (128kB) flash serially but now is couple of seconds. Also speed is increased from 25Mhz to 50Mhz.
I did try ICC and CW. Both worked good for me. In order to start debugging using serial port you need to revise putchar() fun. and include into your code because by some reasons they changed addresses of SCI registers and normal SCI routines would not work if you do not make this change.This is regarding SCI . Other periferals I did not use so far except ADC.
If anybody used CAN I would like to see some examples???

For MEBI interfacing check www.hc12web.de . RAM.Bo256 for
schematic and
