17.4
The Enhanced PWM mode provides additional PWM
output options for a broader range of control applica-
tions. The module is a backward compatible version of
the standard CCP module and offers up to four outputs,
designated PxA through PxD. Users are also able to
select the polarity of the signal (either active-high or
active-low). The module’s output mode and polarity
are configured by setting the PxM1:PxM0 and
CCPxM3CCPxM0 bits of the CCPxCON register
(CCPxCON<7:6> and CCPxCON<3:0>, respectively).
For the sake of clarity, Enhanced PWM mode operation
is described generically throughout this section with
respect to ECCP1 and TMR2 modules. Control register
names are presented in terms of ECCP1. All three
Enhanced modules, as well as the two timer resources,
can be used interchangeably and function identically.
TMR2 or TMR4 can be selected for PWM operation by
selecting the proper bits in T3CON.
Figure 17-1 shows a simplified block diagram of PWM
operation. All control registers are double-buffered and
are loaded at the beginning of a new PWM cycle (the
period boundary when Timer2 resets) in order to pre-
vent glitches on any of the outputs. The exception is the
PWM Delay register, ECCP1DEL, which is loaded at
either the duty cycle boundary or the boundary period
(whichever comes first). Because of the buffering, the
module waits until the assigned timer resets instead of
starting immediately. This means that Enhanced PWM

waveforms do not exactly match the standard PWM
waveforms, but are instead offset by one full instruction

As before, the user must manually configure the
appropriate TRIS bits for output.

The PWM period is specified by writing to the PR2
register. The PWM period can be calculated using the
equation:
EQUATION 17-1:
PWM frequency is defined as 1/[PWM period]. When
TMR2 is equal to PR2, the following three events occur
on the next increment cycle:
• TMR2 is cleared
• The ECCP1 pin is set (if PWM duty cycle = 0%,
• The PWM duty cycle is copied from CCPR1L into
