Table 112. PWM Prescale Clock Select Register (PWMPRCLK)
Note:
Functional Description and Application Information
4.13.3.1.4
The CAEx bits select either center aligned outputs or left aligned output for both PWM channels. If the CAEx bit is set to a one,
the corresponding PWM output will be center aligned. If the CAEx bit is cleared, the corresponding PWM output will be left
aligned. See
description of the PWM output modes.
4.13.3.2
This register selects the prescale clock source for clocks A and B independently.

Prescaler Select for Clock B — Clock B is one of two clock sources which can be used for channel 1. These three bits
determine the rate of clock B, as shown in
Prescaler Select for Clock A — Clock A is one of two clock sources which can be used for channel 0. These three bits
determine the rate of clock A, as shown in
PWM Center Align Enable (CAEx)
Write these bits only when the corresponding channel is disabled.
PCKB2–0 and PCKA2–0 register bits can be written anytime. If the clock pre-scale is
changed while a PWM signal is being generated, a truncated or stretched pulse can occur
during the transition.
