We are porting an application from a 16F887 to a 18F4410. For the Microchip descriptions of how the interrupts function on PORT-B for both devices we find them to be identical. In our app we are looking for a state change on INT-B4...
In the device definition file for the 887 the primary interrupt is defined as:
With no qualification for the Int-On-Change values
Can this be resolved and added to the int-on-change values to the 4410 def file..? _________________ Thank you,

The two PICs don't have the same features. The 16F887 has much more
detailed features for PortB than the 18F4410. The 16F887 has an IOC
register and a WPUB register. The 18F4410 does not.

PCM Programmer,
In description they sound identical, but i missed the fact the the IOCB register is missing in the 4410. I guess bit testing is the only other solution. Thanks for your help.... _________________ Thank you,
