Hi,

I am using a program on a 16F870 where all pins are outputs with the exception of portc.7. I can activate each output one by one and turn them off with no problems. When I try to activate portc.2 and portc.3 with all other outputs active, they only turn others off and I can't understand why. Said differntly, they work fine by themselves but when combined with other outputs, the operation is not what was expected. Can anyone shed some light on this?
