service routine, ISR) that generates an interrupt
when Port H pin 0 becomes a logic 1. Within
this ISR, disable interrupts, clear the interrupt
flag, then enable interrupts, and return from
routine. I also want the routine or lines of C
code that initialize Port H pin 0 to be used as
an interrupt (hint think
