//*********************************************************************************
//Configure a remappable output pin with interrupt capability
//for ULPWU function (RP21 => RD4/INT1 in this example)
//*********************************************************************************
RPOR21 = 13;// ULPWU function mapped to RP21/RD4
RPINR1 = 21;// INT1 mapped to RP21 (RD4)
//***************************
//Charge the capacitor on RA0

TRISAbits.TRISA0 = 0;
PORTAbits.RA0 = 1;
for(i = 0; i < 10000; i++) Nop();
//**********************************
//Stop Charging the capacitor on RA0
//**********************************
TRISAbits.TRISA0 = 1;
//*****************************************
//Enable the Ultra Low Power Wakeup module
//and allow capacitor discharge

INTCON3bits.INT1IF = 0;
INTCON3bits.INT1IE = 1;
//********************
//Configure Sleep Mode
//********************
//For Sleep
OSCCONbits.IDLEN = 0;
//For Deep Sleep
OSCCONbits.IDLEN = 0;// enable deep sleep
DSCONHbits.DSEN = 1;// Note: must be set just before executing Sleep();
//****************
//Enter Sleep Mode
//****************
Sleep();
// for sleep, execution will resume here
// for deep sleep, execution will restart at reset vector (use WDTCONbits.DS to detect)
Enable Interrupt for ULPW.
