Thanks heaps Lars,
I thought I had done something wrong in my porting of the at9can128.asm to
my atmega128.asm file, you are correct temp7 is trashing the zh register, I
confirmed that by
running AVR studio and debugging the code in the simulator. The device
resets each time after DO_EXECUTE, changing to temp5 makes the code run
normal.
I will try it on the mega128 hardware when I get home tonight.
I notice that both temp6 and temp7 overlap r30/r31 so maybe we need to get
rid of both temp6 and temp7.....
Regards,
Bernard.
