HC912B32 memory map

Yuping — Thu, 29 Oct 2009 04:48:35 GMT

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:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=68HC912B32&fpsp=1&tab=Documentation_Tab

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.

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!
