flash document for 9S12HZ256

Started by jetrimmer September 7, 2005
Hello:
I'm looking for information regarding the flash module in the new
part
9S12HZ256.
I think it has 2 flash arrays (64K * 16 bits).

The older 9S12H256 has 4 flash arrays 32K * 16 bits.
My flash programming code that works with the 9S12H256 is not working
with the new one.

Thanks.



Hi.

You can download the following ZIP and have a look in the
"S12FTS256K2ECCV1.pdf" file for blocks organization.
However, the "Error Code Correction (ECC)" feature does not apply to HZ flash.

For sure, FCNFG register, BKSEL bit(s) setup is different.
