10.3
The PWM mode generates a Pulse-Width Modulated
signal on the CCP1 pin. The duty cycle, period and
resolution are determined by the following registers:
• PR2
• T2CON
• CCPR1L
• CCP1CON
In Pulse-Width Modulation (PWM) mode, the CCP
module produces up to a 10-bit resolution PWM output
on the CCP1 pin. Since the CCP1 pin is multiplexed
with the PORT data latch, the TRIS for that pin must be
cleared to enable the CCP1 pin output driver.
Figure 10-3 shows a simplified block diagram of PWM
operation.
Figure 10-4 shows a typical waveform of the PWM
signal.
For a step-by-step procedure on how to set up the CCP
module for PWM operation, see Section 10.3.7
“Setup for PWM Operation”.

Clearing the CCP1CON register will
relinquish CCP1 control of the CCP1 pin.
The 8-bit timer TMR2 register is concatenated
with the 2-bit internal system clock (F
2 bits of the prescaler, to create the 10-bit time
base.
In PWM mode, CCPR1H is a read-only register.

The PWM output (Figure 10-4) has a time base
(period) and a time that the output stays high (duty
cycle).
