11.4.2
When any PWM mode is used, the application
hardware must use the proper external pull-up and/or
pull-down resistors on the PWM output pins.
The CCP1M<1:0> bits of the CCP1CON register allow
the user to choose whether the PWM output signals are
active-high or active-low for each PWM output pin (P1A
and P1B). The PWM output polarities must be selected
before the PWM pin output drivers are enabled.
Changing the polarity configuration while the PWM pin
output drivers are enable is not recommended since it
may result in damage to the application circuits.
The P1A and P1B output latches may not be in the proper
states when the PWM module is initialized. Enabling the
PWM pin output drivers at the same time as the
Enhanced PWM modes may cause damage to the
application circuit. The Enhanced PWM modes must be
enabled in the proper Output mode and complete a full
PWM cycle before configuring the PWM pin output
drivers. The completion of a full PWM cycle is indicated
by the TMR2IF bit of the PIR1 register being set as the
second PWM period begins.
11.4.3
When the device is placed in sleep, the allocated timer
will not increment and the state of the module will not
change. If the CCP1 pin is driving a value, it will
continue to drive that value. When the device wakes
up, it will continue from this state.

Note:
START-UP CONSIDERATIONS
When the microcontroller is released from
Reset, all of the I/O pins are in the high-
impedance state. The external circuits
must keep the power switch devices in the
OFF state until the microcontroller drives
the I/O pins with the proper signal levels or
activates the PWM output(s).
