Darrel, I know this statement was related to a posting for a 18F66J15, but I am trying to use RBC_INT for PortB.2 and PortB.3 on a 16F886. I had a design going on a 18F2550 that used INT2_INT on PortB2 and worked well. However, for reasons I won't go into here I had to move the design to a 16F886 and continue to use PortB.2 and PortB.3 as interrupt inputs from the alarm pins on a DS1337 RTC. I already have PCBs built originally for the 28-pin 18F2550 and am trying to salvage them without trace changes by substituting a 28-pin 16F886 on the same board layout. My question...is there anyway I can use RBC_INT on the PortB.2 and PortB.3 pins of a 16F886 and monitor which pin actually received the interrupt? I have noted your OLDPORT vs NEWPORT technique to do this kind of interrupt isolation and presume I can do this on my 16F886 if RBC_INT will work ont these ports? Can you help me out here?
