//First, check if the interrupt occurred as a result of an
//RA2 change interrupt. If so, clear the RABIF flag so
//that subsequent interrupts can occur
if(RABIE && RABIF) RABIF = 0;
//Check the push button connected to RA0 pin. If 0, then a
//push button press is indicated
//if RA2 is still 0 then change the direction flag
//Check the push button connected to RA0 pin. If 1, then a
//push button release is indicated
//if RA2 is still 1 then change the direction flag
//Otherwise, keep the direction bit the same as it was
//Read PORTA to latch RA2 value for the next interrupt
from the previous lab.
