13.4.2
The PWM period is specified by writing to the PRx
register. The PWM period can be calculated using
Equation 13-1.
EQUATION 13-1:
PWM frequency is defined as 1/[PWM period].

When the CPU enters Sleep mode, all internal clocks
are stopped. Therefore, when the CPU enters the
Sleep state, the output compare channel will drive the
pin to the active state that was observed prior to
entering the CPU Sleep state.
For example, if the pin was high when the CPU entered
the Sleep state, the pin will remain high. Likewise, if the
pin was low when the CPU entered the Sleep state, the
pin will remain low. In either case, the output compare
module will resume operation when the device wakes
up.
13.6
When the CPU enters the Idle mode, the output
compare module can operate with full functionality.
The output compare channel will operate during the
CPU Idle mode if the OCSIDL bit (OCxCON<13>) is at
logic ‘0’ and the selected time base (Timer2 or Timer3)
is enabled and the TSIDL bit of the selected timer is set
to logic ‘0’.

When the selected TMRx is equal to its respective
period register, PRx, the following four events occur on
the next increment cycle:
• TMRx is cleared.
• The OCx pin is set.
• The PWM duty cycle is latched from OCxRS into
• The corresponding timer interrupt flag is set.
See Figure 13-2 for key PWM period comparisons.
Timer3 is referred to in Figure 13-2 for clarity.

The output compare channels have the ability to gener-
ate an interrupt on a compare match, for whichever
Match mode has been selected.
For all modes except the PWM mode, when a compare
event occurs, the respective interrupt flag (OCxIF) is
asserted and an interrupt will be generated if enabled.
The OCxIF bit is located in the corresponding IFS
Status register and must be cleared in software. The
interrupt is enabled via the respective compare inter-
rupt enable (OCxIE) bit located in the corresponding
IEC Control register.
For the PWM mode, when an event occurs, the respec-
tive timer interrupt flag (T2IF or T3IF) is asserted and
an interrupt will be generated if enabled. The IF bit is
located in the IFS0 Status register and must be cleared
in software. The interrupt is enabled via the respective
timer interrupt enable bit (T2IE or T3IE) located in the
IEC0 Control register. The output compare interrupt
flag is never set during the PWM mode of operation.

- Exception 2: If duty cycle is greater than PRx,
