Pulse-Width Modulator (S12PWM8B8CV2)
19.3.2.5
The PWMCAE register contains eight 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 one, the corresponding PWM output will be
center aligned. If the CAEx bit is cleared, the corresponding PWM output will be left aligned. See
Section 19.4.2.5, “Left Aligned Outputs”
detailed description of the PWM output modes.

Prescaler Select for Clock B — Clock B is one of two clock sources which can be used for all channels. 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 all channels. These
three bits determine the rate of clock A, as shown in
