The CCP1M<1:0> bits in the CCP1CON register allow
user to choose the logic conventions (asserted high/
low) for each of the outputs. See Register 8-1 for fur-
ther details.

The PWM output polarities must be selected before the
PWM outputs are enabled. Charging the polarity con-
figuration while the PWM outputs are active is not rec-
ommended, since it may result in unpredictable
operation.
