>I am having difficulty emulating with a PIC16C74.  I am using a RICE16
emulator, and looking for a change in PORTB.  I have set INTCON to a hex C8,
and PB2 thru PB7 are setup for input, with weak pullups.  When I ground PB4,
the emulator processes the interrupt, but performing a read on PORTB does
not enable me to clear bit 0 of INTCON.  Can anyone help me with this problem?

>If the input is transient, and returns to '1' immediately during the
interrupt there is no problem, but if the input remains at '0', difficulties
ensue.
