PWM (Enhanced Mode)
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
To select an Enhanced PWM mode, the P1M bits of the
CCP1CON register must be set appropriately.
The PWM outputs are multiplexed with I/O pins and are
designated P1A and P1B. The polarity of the PWM pins
is configurable and is selected by setting the CCP1M
bits in the CCP1CON register appropriately.
Table 10-6 shows the pin assignments for each
Enhanced PWM mode.
Figure 10-5 shows an example of a simplified block
diagram of the Enhanced PWM module.

first enabled, the ECCP module waits until

generating a PWM signal.
