18.0
In the PIC18F8722 family of devices, ECCP1, ECCP2
and ECCP3 are implemented as a standard CCP
module 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.

The control register for the Enhanced CCP modules is
shown in Register 18-1. It differs from the CCPxCON
registers
Compare/PWM (CCP) Modules” 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
features associated with Enhanced PWM operation
and auto-shutdown features. They are:
• ECCPxDEL (Dead-Band Delay)
• ECCPxAS (Auto-Shutdown Configuration)
