The debugger should update all changed registers after every single-step. It should also update the registers if I force a refresh. The problem is that it doesn't. I change the signal on the input pin (RC1) and single-step any number of times, but the PORTC register doesn't update until I single-step over the RB1 =3D RC1 line. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
