Hi,

 

I am really a newbie...

I want to know what exactly are there in the memory. I could only find a very simple one like in the book "Software and Hardware Engineering" by Fredrick M. Cady. I want to have a detailed one which tells you what are the addresses for different interrupt vectors and control registers.

 

Btw, how could I load my program to the Flash memory?

 

Thanks!

If you are newbie, then why not start with current S12/S12X chips?

 

Vector table, register addresses, peripheral manuals all should be found in M68HC12B family datasheet:

Also have a look at other documents:

P&E USB-ML-12 + Codewarrior  should be enough for all current S08/RS08/S12/S12X/Coldfire_V1 chips. As far as I remember, old 912B32 requires also 12V programming voltage. In contrast to RS08, for which RevC and more recent USB-ML-12 can provide programming voltage via /RESET pin, which is available in standard BDM connector; B32 requires Vpp on some other pin. Good reason to start with more fresh chips!

Hi Kef,

 

Thanks a lot for the information!! Seems I have a lot of work to do now. :smileyhappy:

X68HC912B32 is the only one available for me here. I did not know it's so old at first...

Anyway, I'll have to study more about it.

 

Thanks!
