Jan-Erik,
     Something is wrong. I should be getting a one second high on RC4=20
every 15.x seconds. Where x is just a few uSs. I should then get a very=20
short pulse on RC5 also every 15.x seconds. I'm not getting these. I=20
have it narrowed down to the delay and the interrupt not working.
     Here are the bits for CMCON0 and ANSEL in that order. They are:=20
0b00000111 and 0b00010000. This is a 16f684. I've gone through it at=20
least a dozen different times. I tried the suggestions that James has=20
made and they haven't worked. Hum, I'm lost right now. I'm sorry for=20
being a pain.
Thanks,
rich!
