The Enhanced PWM mode can generate a PWM signal
on up to four different output pins with up to 10 bits of
resolution. It can do this through four different PWM
Output modes:
• Single PWM
• Half-Bridge PWM
• Full-Bridge PWM, Forward mode
• Full-Bridge PWM, Reverse mode
To select an Enhanced PWM mode, the PxM bits of the
CCPxCON register must be set appropriately.

The PWM outputs are multiplexed with I/O pins and are
designated: PxA, PxB, PxC and PxD. The polarity of the
PWM pins is configurable and is selected by setting the
CCPxM bits in the CCPxCON register appropriately.
Table 19-1 provides the pin assignments for each
Enhanced PWM mode.
Figure 19-3 provides an example of a simplified block
diagram of the Enhanced PWM module.
