PIC18F66K80 FAMILY
19.4
In Pulse-Width Modulation (PWM) mode, the CCPx pin
produces up to a 10-bit resolution PWM output. Since
the CCPx pin is multiplexed with a PORTC or PORTB
data latch, the appropriate TRIS bit must be cleared to
make the CCPx pin an output.
Figure 19-3
CCPx module in PWM mode.
For a step-by-step procedure on how to set up the CCP
module for PWM operation, see
“Setup for PWM Operation”

PWM Mode
The 8-bit TMR2 value is concatenated with the 2-bit
internal Q clock, or 2 bits of the prescaler, to create
the 10-bit time base.
CCP4 and its appropriate timers are used as an
example. For details on all of the CCP modules and
their timer assignments, see
Clearing the CCPxCON register will force
the corresponding CCPx output latch
(depending on device configuration) to the
default low level. This is not the PORTx
I/O data latch.

Preliminary
A PWM output
and a time that the output stays high (duty cycle). The
frequency of the PWM is the inverse of the period
(1/period).
FIGURE 19-4:
19.4.1
The PWM period is specified by writing to the PR2
register. The PWM period can be calculated using the
following formula:
EQUATION 19-1:
PWM frequency is defined as 1/[PWM period].
When TMR2 is equal to PR2, the following three events
occur on the next increment cycle:
• TMR2 is cleared
• The CCP4 pin is set
• The PWM duty cycle is latched from CCPR4L into
(An exception: If PWM duty cycle = 0%, the CCP4
pin will not be set)

PWM Period = [(PR2) + 1] • 4 • T

Section 15.0 “Timer2 Module”

frequency. The postscaler could be used
to have a servo update rate at a different
frequency than the PWM output.
