16.0
In 40 and 44-pin devices, the CCP1 module is
implemented as a standard CCP module with
enhanced PWM capabilities. Operation of the Capture,
Compare and standard single output PWM modes is
described in Section 15.0 “Capture/Compare/PWM
(CCP) Modules”. Discussion in that section relating to
PWM frequency and duty cycle also apply to the
enhanced PWM mode.

P1M1:P1M0: PWM Output Configuration bits
If CCP1M<3:2> = 00, 01, 10 (Capture, Compare, or disabled):
xx = P1A assigned as Capture/Compare input; P1B, P1C, P1D assigned as port pins
If CCP1M<3:2> = 11 (PWM modes):
00 = Single output; P1A modulated; P1B, P1C, P1D assigned as port pins
01 = Full-bridge output forward; P1D modulated; P1A active; P1B, P1C inactive
10 = Half-bridge output; P1A, P1B modulated with dead band control; P1C, P1D assigned as port pins
11 = Full-bridge output reverse; P1B modulated; P1C active; P1A, P1D inactive

These bits are the two LSbs of the PWM duty cycle. The eight MSbs are found in CCPR1L.

The ECCP module differs from the CCP with the addi-
tion of an enhanced PWM mode which allows for 2 or
4 output channels, user-selectable polarity, dead band
control and automatic shutdown and restart. These
features are discussed in detail in Section 16.4
“Enhanced PWM Mode”.
The control register for CCP1 is shown in Register 16-1.
It differs from the CCP1CON register of PIC18F2X20
devices in that the two Most Significant bits are
implemented to control enhanced PWM functionality.
