If you know of any more gotchas with the HC12 in expanded wide, let me
know.
Thanks,

Heath,
You're in expanded wide mode. Is this a 16 bit wide EEPROM?
If you're in wide mode, set LSTRE in the PEAR register. You need the
/LSTRB signal to do byte-wide writes to external wide memories.

Hello,
I am having trouble getting the Hc12 A4 chip to work in expanded wide
mode. Specifically I am having problems reading and or writing to an
eeprom, which has been checked manually and is working correctly. When
trying to read from the EEPROM only the even addresses are being read
correctly. My output is included.
I have set the mode, windef, chip select, and pear registers on init.
Any ideas would be great.
