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.

If CCPxM<3:2> = 00, 01, 10:
xx = PxA assigned as Capture/Compare input/output; PxB, PxC, PxD assigned as port pins
If CCPxM<3:2> = 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

These bits are the two LSbs of the 10-bit PWM duty cycle. The eight MSbs of the duty cycle are found
in CCPRxL.

1001 = Compare mode: initialize ECCPx pin high; clear output on compare match (set CCPxIF)
1010 = Compare mode: generate software interrupt only; ECCPx pin reverts to I/O state
1011 = Compare mode: trigger special event (ECCP resets TMR1 or TMR3, sets CCPxIF bit; ECCP2

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)
