EXAMPLE 4-5:
//Configure RC0,RC1,RC2 and RC3 as digital outputs
//Initialize PORTA pin connected to C12IN0-
//Make C1OUT pin an output
//Configure the Comparator 1 as follows:
//Turn on comparator 1
//Make C1OUT available externally
//Connect the non-inverting reference to CVREF
//Connect the inverting reference to C12IN0-
//Configure the CVREF as follows:
//Route CVREF output to Comparator 1 non-inverting reference
//Enable the 0.6V fixed reference voltage
//Configure Timer1 as follows
//Make T1CKI and input
//Select T1CKI as Timer1's clock source
//Initialize the 16-bit Timer1 register pair to 0
//Turn on Timer1
//Set up Timer0 as follows:
//Use FOSC/4 for Timer0 Clock Source
//assign the prescaler to TMR0
//set up prescaler for 1:256
//Enable Timer0 Interrupts
//Clear the Timer0 overflow interrupt flag
//Preload TMR0 with 10 to keep overflow period
//less than Timer1 overflow period
//Enable global interrupts
