15.0
PIC18F2420/2520/4420/4520 devices all have two
CCP (Capture/Compare/PWM) modules. Each module
contains a 16-bit register which can operate as a 16-bit
Capture register, a 16-bit Compare register or a PWM
Master/Slave Duty Cycle register.
In 28-pin devices, the two standard CCP modules (CCP1
and CCP2) operate as described in this chapter. In 40/
44-pin devices, CCP1 is implemented as an Enhanced
CCP module with standard Capture and Compare
modes and Enhanced PWM modes. The ECCP imple-
mentation is discussed in Section 16.0 “Enhanced
Capture/Compare/PWM (ECCP) Module”.

The capture and compare operations described in this
chapter apply to all standard and Enhanced CCP
modules.
Note: Throughout this section and Section 16.0
“Enhanced Capture/Compare/PWM (ECCP)
Module”, references to the register and bit
names for CCP modules are referred to gener-
ically by the use of ‘x’ or ‘y’ in place of the
specific module number. Thus, “CCPxCON”
might refer to the control register for CCP1,
CCP2 or ECCP1. “CCPxCON” is used
throughout these sections to refer to the mod-
ule control register, regardless of whether the
CCP module is a standard or enhanced
implementation.
