I would like to program in circuit, the list of these microcontrollers:

MC68HC05xxx

MC68HC08xxx

MC68HC908xx

MC68HC912xx

and

MC9S12xxx

 

I need documentation explaining the algorithms to use (serial or JTAG or etc ...) and what connections do.

Thank you very much for helping.

Hi VIncenzo,

I don't have much experience with old 8-bit MCUs, but for the HC12 and S12 devices here is some useful info:
Using Background Debug Mode for the M68HC12 Family


More application notes about programming you can find under documentation tab:

S12D MCUs|16-Bit Microcontroller|NXP

Also, in this S12XE reference manual there are chapters 7 and 8 describing S12X BDM and Debug modules:

S12XE MCUs|16-Bit Microcontroller|NXP

Hope the information helps.

Regards,

iggi
