PIC16F707/PIC16LF707
17.3.2
The PWM period is specified by the PR2 register of
Timer2. The PWM period can be calculated using the
formula of Equation 17-1.
EQUATION 17-1:
When TMR2 is equal to PR2, the following three events
occur on the next increment cycle:
• TMR2 is cleared
• The CCPx pin is set. (Exception: If the PWM duty
• The PWM duty cycle is latched from CCPRxL into
17.3.3
The PWM duty cycle is specified by writing a 10-bit value
to multiple registers: CCPRxL register and DCxB<1:0>
bits of the CCPxCON register. The CCPRxL contains
the eight MSbs and the DCxB<1:0> bits of the
CCPxCON register contain the two LSbs. CCPRxL and
DCxB<1:0> bits of the CCPxCON register can be written
to at any time. The duty cycle value is not latched into
CCPRxH until after the period completes (i.e., a match
between PR2 and TMR2 registers occurs). While using
the PWM, the CCPRxH register is read-only.
Equation 17-2 is used to calculate the PWM pulse
width.
Equation 17-3 is used to calculate the PWM duty cycle
ratio.

EQUATION 17-2:
EQUATION 17-3:
The CCPRxH register and a 2-bit internal latch are
used to double buffer the PWM duty cycle. This double
buffering is essential for glitchless PWM operation.
The 8-bit timer TMR2 register is concatenated with
either the 2-bit internal system clock (F
the prescaler, to create the 10-bit time base. The system
clock is used if the Timer2 prescaler is set to 1:1.
When the 10-bit time base matches the CCPRxH and
2-bit latch, then the CCPx pin is cleared (refer to
Figure 17-3).
