To validate a serial data sequence I was holding the isr measuring
pulse width without ccp option. I might have gotten only one more int
during this time, so didn't worry about stack.

I don't like to enable gie within isr but it was more intuitive to
program and timings were more accurate. I am not sure whether it can
always be avoided.
