EXAMPLE 3-24:
It should be noted that the Global Interrupt Enable bit (GIE) is set last in the
Example 3-24. This ensures that interrupts will not occur during the Initialize(),
having adverse consequences on code operation.

//Clear PORTC to a known state
//Set the least significant bit to 1 so that it can be
//shifted through
//Clear the PORTA register to a known state
//Configure PORTC's ANALOG/DIGITAL pins as all Digital
//Configure PORTC pins as all output
//i.e. 1 = Input, 0 = Output
//Configure PORTA bit RA0 as Digital input
//Configure Timer0 to overflow every 5mS
//Select a 1:32 prescaler
//Initialize the direction flag to shift bits from
//right-to-left
//(i.e. 0 = Shift PORTC bits from right-to-left
//
//Initialize LED_Output to all zeros
//Configure for external interrupts on RA2
