PIC18F47J53 FAMILY DS39964B-page 62 Preliminary 2010 Microchip Technology Inc. EXAMPLE 4-1: ULTRA LOW-POWER WAKE-UP INITIALIZATION //********************************************************************************* //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 //***************************************** WDTCONbits.ULPEN = 1; WDTCONbits.ULPSINK = 1; //****************************************** //Enable Interrupt for ULPW //****************************************** //For Sleep //(assign the ULPOUT signal in the PPS module to a pin //which has also been assigned an interrupt capability, //such as INT1) 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) |
