18.0
In the PIC18F87J11 family of devices, three of the CCP
modules are implemented as standard CCP modules
with Enhanced PWM capabilities. These include the
provision for 2 or 4 output channels, user-selectable
polarity, dead-band control and automatic shutdown
and restart. The Enhanced features are discussed in
detail in Section 18.4 “Enhanced PWM Mode”.
Capture, Compare and single-output PWM functions of
the ECCP module are the same as described for the
standard CCP module.

PxM1:PxM0: Enhanced PWM Output Configuration bits
If CCPxM3:CCPxM2 = 00, 01, 10:
xx = PxA assigned as Capture/Compare input/output; PxB, PxC, PxD assigned as port pins
If CCPxM3:CCPxM2 = 11:
00 = Single output: PxA modulated; PxB, PxC, PxD 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

The control register for the Enhanced CCP module is
shown in Register 18-1. It differs from the CCP4CON/
CCP5CON registers in that the two Most Significant
bits are implemented to control PWM functionality.
In addition to the expanded range of modes available
through the Enhanced CCPxCON register, the ECCP
modules each have two additional registers associated
with Enhanced PWM operation and auto-shutdown
features. They are:
• ECCPxDEL (ECCPx PWM Delay)
• ECCPxAS (ECCPx Auto-Shutdown Control)
