PIC18F2220/2320/4220/4320
REGISTER 16-1:
In addition to the expanded functions of the CCP1CON
register, the ECCP module has two additional registers
associated with enhanced PWM operation and
Auto-Shutdown features:
• PWM1CON
• ECCPAS
All other registers associated with the ECCP module are
identical to those used for the CCP1 module in
PIC18F2X20 devices, including register and individual bit
names. Likewise, the timer assignments and interactions
between the two CCP modules are identical, regardless
of whether CCP1 is a standard or enhanced module.
16.1
The Enhanced CCP module may have up to four outputs
depending on the selected operating mode. These out-
puts, designated P1A through P1D, are multiplexed with
I/O pins on PORTC and PORTD. The pin assignments
are summarized in Table 16-1.
To configure I/O pins as PWM outputs, the proper PWM
mode must be selected by setting the P1Mx and
CCP1Mx bits (CCP1CON<7:6> and <3:0>, respec-
tively). The appropriate TRISC and TRISD direction
bits for the port pins must also be set as outputs.

TRIS register values must be configured appropriately.
With ECCP in Dual or Quad PWM mode, the PSP input/output control of PORTD is overridden by P1B,
P1C and P1D.

16.2
The Capture and Compare modes of the ECCP module
are identical in operation to that of CCP1, as discussed
in Section 15.3 “Capture Mode” and Section 15.4
“Compare Mode”. No changes are required when
moving between these modules on PIC18F2X20 and
PIC18F4X20 devices.
16.3
When configured in Single Output mode, the ECCP
module functions identically to the standard CCP
module in PWM mode, as described in Section 15.4
“Compare Mode”.

RD5/PSP5
When setting up single output PWM opera-
tions, users are free to use either of the pro-
cesses described in Section 15.5.3 “Setup
for PWM Operation” or Section 16.4.7
“Setup for PWM Operation”. The latter is
more generic but will work for either single
or multi output PWM.
