In PWM mode, the output compare module can be
configured for edge-aligned or center-aligned pulse
waveform generation. All PWM operations are
double-buffered (buffer registers are internal to the
module and are not mapped into SFR space).

Calculate the desired period and load it into the
OCxRS register.
Select the current OCx as the synchronization
source by writing 0x1F to SYNCSEL<4:0>

Select
OCTSEL2<2:0> (OCxCON<12:10>) bits.
Enable interrupts, if required, for the timer and
output compare modules. The output compare
interrupt is required for PWM Fault pin utilization.
Select the desired PWM mode in the OCM<2:0>
(OCxCON1<2:0>) bits.
If a timer is selected as a clock source, set the
TMRy prescale value and enable the time base by
setting the TON (TxCON<15>) bit.
