In addition to the expanded range of modes available
through the CCP1CON register and ECCP1AS
register, the ECCP module has two additional registers
associated with Enhanced PWM operation and
auto-shutdown features. They are:
• PWM1CON (Dead-band delay)
• PSTRCON (output steering)
14.1
The enhanced CCP module may have up to four PWM
outputs, depending on the selected operating mode.
These outputs, designated P1A through P1D, are
multiplexed with I/O pins on PORTD. The outputs that
are active depend on the CCP operating mode
selected. The pin assignments are summarized in
Table 14-2.
To configure the I/O pins as PWM outputs, the proper
PWM mode must be selected by setting the P1M<1:0>
and CCP1M<3:0> bits. The appropriate TRISD
direction bits for the port pins must also be set as
outputs.
14.1.1
The CCP modules utilize Timers 1, 2 or 3, depending
on the mode selected. Timer1 and Timer3 are available
to modules in Capture or Compare modes, while
Timer2 is available for modules in PWM mode.
TABLE 14-1:
The assignment of a particular timer to a module is
determined by the Timer-to-CCP enable bits in the
T3CON register (Register 13-1). The interactions

capture operation will not work reliably.
