Re: PortB Interrupt-On-Change problems on PIC18F65J11
Thanks for the quick reply.
OK - I do have the issue on the PIC18F65J11. But to my understanding I am not polling the port. I made sure that during normal execution no reads are done on PortB. Only once the IOC triggered and execution is in the ISR the pins RB4 and RB5 get read to see if they are low. IMO polling is constantly reading the state of the port.
Anyway - reading the port a second time as suggested doesn't solve the problem. Every now and then the system misses a state change on RB4 or RB5.
