PIC18F97J94 family devices have three Enhanced
Capture/Compare/PWM (ECCP) modules: ECCP1,
ECCP2 and ECCP3. These modules contain 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. These ECCP modules are upward
compatible with CCP

ECCP1, ECCP2 and ECCP3 are implemented as stan-
dard CCP modules with enhanced PWM capabilities.
These include:
• Provision for two or four output channels
• Output Steering modes
• Programmable polarity 
• Programmable dead-band control
• Automatic shutdown and restart
The enhanced features are discussed in detail in

The ECCP1, ECCP2 and ECCP3 modules use the
ECCP Control registers, CCP1CON, CCP2CON and
CCP3CON. The control registers, CCP4CON through
CCP10CON, are for the modules, CCP4 through
CCP10.

 

Throughout this section, generic references
are used for register and bit names that are
the same, except for an ‘x’ variable that indi-
cates the item’s association with the CCP1,
CCP2 or CCP3 module. For example, the
control register is named CCPxCON and
refers to CCP1CON, CCP2CON and
CCP3CON.
