Has anyone else noticed while doing a single "debug step" using an ICD, TMR0 just keeps running ? What I mean is, it appears the TMR0 value in the SFR window will jump to any value when Ive only done one instruction step. Timers 1 & 2 on the other hand, are working perfectly. There doesnt seem to be any mention of the debug function using up a timer in the ICD help file either. anyone else notice this? or am I doing something wrong. -- http://www.piclist.com hint: The PICList is archived three different ways.
