12.3.2.5
The PWMCAE register contains six control bits for the selection of center aligned outputs or left aligned
outputs for each PWM channel. If the CAEx bit is set to a 1, the corresponding PWM output will be center
aligned. If the CAEx bit is cleared, the corresponding PWM output will be left aligned. Reference
Section 12.4.2.5, “Left Aligned Outputs,”
detailed description of the PWM output modes.

Prescaler Select for Clock B — Clock B is 1 of two clock sources which can be used for channels 2 or 3. These
three bits determine the rate of clock B, as shown in
Prescaler Select for Clock A — Clock A is 1 of two clock sources which can be used for channels 0, 1, 4, or 5.
These three bits determine the rate of clock A, as shown in
