PIC18F4620 INT_RB question.

[jwt2368]

I would like to utilize a portb on change interrupt.
The CCS manual says: "#INT_RB Port B any change on B4-B7".

Does this apply also to the 18F4620? It would seem logical that the interrupt should detect any pin on port b. B4-B7 limits the amount of inputs I want to detect using the ISR.

If this is indeed the case, can B6 and B7 be used as inputs when they are also used for ICSP (PGC & PGD)? Is it okay to attach buttons to these pins and use the ISR to detect off of them?

I am using the internal portb pullups and a simple spst push button to pull the inputs low when the spst's are pressed.

Thanks,
