Hi Wade,
If you use the D64 documentation from Freescale site, it is a little bit too
old and incomplete - I'm using for instance that for GC128 micro, which
is more

/RESET, reset chip generates its own pull-low pulse and HC12 decides that
reset wasn't internal and ... Re: D64 COP: the saga continues

Hello,
today while working on ColdFire microchip with Freescale Codewarrior
6.4 I encountered a problem.
Lets say one function is composed of other functions, and when I

Hi Wade,
Can you tell us how did you configured your hardware reset circuit
for the microprocessor?
Regards,

for our new product and I'm having an intermittent problem with my FW
downloads. It appears that in some c...
