Depending on the particular device, PIC24F16KL402
family devices include up to three CCP and/or ECCP
modules. Key features of all CCP modules include:
• 16-bit input capture for a range of edge events
• 16-bit output compare with multiple output options
• Single-output Pulse Width Modulation (PWM) with

• 16-bit input capture for a range of edge events
• 16-bit output compare with multiple output options
• Single-output Pulse Width Modulation (PWM) with
up to 10 bits of resolution
• User-selectable time base from any available

ECCP modules also include these features:
• Operation in Half-Bridge and Full-Bridge (Forward
• Operation in Half-Bridge and Full-Bridge (Forward
and Reverse) modes
• Pulse steering control across any or all Enhanced

Timer Selection
On all PIC24F16KL402 family devices, the CCP and
ECCP modules use Timer3 as the time base for cap-
ture and compare operations. PWM and Enhanced
PWM operations may use either Timer2 or Timer4.
PWM time base selection is done through the
CCPTMRS0 register (

CCP I/O Pins
To configure I/O pins with a CCP function, the proper
mode must be selected by setting the CCPxM<3:0>
bits.
Where the Enhanced CCP module is available, it may
have up to four PWM outputs, depending on the
selected operating mode. These outputs are desig-
nated, P1A through P1D. The outputs that are active
depend on the ECCP operating mode selected. To
configure I/O pins for Enhanced PWM operation, the
proper PWM mode must be selected by setting the
PM<1:0> and CCPM<3:0> bits.
