// Example code for Output Compare 1 ISR:
#pragma interupt OC1IntHandler ipl4 vector 36
void OC1IntHandler(void)
{
}
The following code example will set the Output Compare 1 module
for PWM mode with FAULT pin disabled, a 50% duty cycle and a
PWM frequency of 52.08 kHz at F
the clock for the PWM time base and Output Compare 1 interrupts
are enabled.
OC1CON = 0x0000;
OC1R = 0x00600000;
OC1RS = 0x00600000;
OC1CON = 0x0006;
PR2 = 0x00600000;
IFS0 &= ~0x00000080;
IEC0 |= 0x00000080;
IPC1 |= 0x001C0000;
IPC1 |= 0x00000003;
T2CON |= 0x8000;
OC1CON |= 0x8000;

PWM MODE PULSE SETUP AND INTERRUPT SERVICING (32-BIT MODE)
IFS0CLR = 0x00000080; // Clear the interrupt flag
// Turn off OC1 while doing setup.
// Initialize primary Compare Register
// Initialize secondary Compare Register
// Configure for PWM mode, Fault pin Disabled
// Set period
// configure int
// Clear the OC1 interrupt flag
// Enable OC1 interrupt
// Set OC1 interrupt priority to 7,
// the highest level
// Set subpriority to 3, maximum
// Enable timer2
// turn on OC1 module
