Code:

#include <xc.h>
// Configuration Bits to make the part run from Internal FRCDIV
// Oscillator.
_FBS
(
BWRP_OFF & // Boot Segment Write Protect (Disabled)
BSS_OFF // Boot segment Protect (No boot flash segment)
)
_FGS
(
GWRP_OFF & // General Segment Flash Write Protect (General segment may be written)
GSS0_OFF // General Segment Code Protect (No Protection)
)
_FOSCSEL
(
FNOSC_FRCDIV & // Oscillator Select (8MHz FRC with Postscaler (FRCDIV))
SOSCSRC_ANA & // SOSC Source Type (Analog Mode for use with crystal)
LPRCSEL_HP & // LPRC Power and Accuracy (High Power/High Accuracy)
IESO_ON // Internal External Switch Over bit (Internal External Switchover mode enabled (Two-speed Start-up enabled))
)
_FOSC
(
POSCMD_NONE & // Primary Oscillator Mode (Primary oscillator disabled)
OSCIOFNC_ON & // CLKO Enable Configuration bit (CLKO output signal enabled)
POSCFREQ_MS & // Primary Oscillator Frequency Range Configuration bits (Primary oscillator/external clock frequency between 100kHz to 8MHz)
SOSCSEL_SOSCHP &// SOSC Power Selection Configuration bits (Secondary Oscillator configured for high-power operation)
FCKSM_CSECME // Clock Switching and Monitor Selection (Clock Switching and Fail-safe Clock Monitor Enabled)
)
_FWDT
(
WDTPS_PS32768 & // Watchdog Timer Postscale Select bits (1:32768)
FWPSA_PR128 & // WDT Prescaler bit (WDT prescaler ratio of 1:128)
FWDTEN_OFF & // Watchdog Timer Enable bits (WDT disabled in hardware; SWDTEN bit disabled)
WINDIS_OFF // Windowed Watchdog Timer Disable bit (Standard WDT selected (windowed WDT disabled))
)
// Warning:
// Always enable MCLRE_ON config bit setting so that the MCLR pin function will
// work for low-voltage In-Circuit Serial Programming (ICSP). The Microstick
// programming circuitry only supports low-voltage ICSP. If you disable MCLR pin
// functionality, a high-voltage ICSP tool will be required to re-program the
// part in the future.
_FPOR
(
BOREN_BOR3 & // Brown-out Reset Enable bits (Enabled in hardware; SBOREN bit disabled)
PWRTEN_ON & // Power-up Timer Enable (PWRT enabled)
I2C1SEL_PRI & // Alternate I2C1 Pin Mapping bit (Default SCL1/SDA1 Pins for I2C1)
BORV_V18 & // Brown-out Reset Voltage bits (Brown-out Reset at 1.8V)
MCLRE_ON // MCLR Pin Enable bit (RA5 input disabled; MCLR enabled)
)
_FICD
(
ICS_PGx3 // ICD Pin Placement Select (EMUC/EMUD share PGC3/PGD3)
)
void DelaymS(unsigned int del)
{
unsigned int j;
while(del--)
for(j=0;j<1600;j++);
}
int main(void)
{
unsigned int i;
// Set up output pin for LED
TRISAbits.TRISA0 = 0;
while(1)
{
// (insert your application code here)
DelaymS(500);
// Toggle the LED output pin to alternate between the LED being on and off
LATAbits.LATA0 ^= 1;
