Read and write anytime.
The value in each duty register determines the duty of the associated PWM channel. When the duty
value is equal to the counter value, the output changes state. If the register is written while the channel
is enabled, the new value is held in a buffer until the counter rolls over or the channel is disabled. Read-
ing this register returns the most recent value written.
If the duty register is greater than or equal to the value in the period register, there will be no duty change
in state. If the duty register is set to $FF the output will always be in the state which would normally be
the state opposite the PPOLx value.

PSWAI — PWM Halts while in Wait Mode
0 = Allows PWM main clock generator to continue while in wait mode.
1 = Halt PWM main clock generator when the part is in wait mode.
CENTR — Center-Aligned Output Mode
To avoid irregularities in the PWM output mode, write the CENTR bit only when PWM channels are dis-
abled.
0 = PWM channels operate in left-aligned output mode
1 = PWM channels operate in center-aligned output mode
RDPP — Reduced Drive of Port P
0 = All port P output pins have normal drive capability.
1 = All port P output pins have reduced drive capability.
PUPP — Pull-Up Port P Enable
0 = All port P pins have an active pull-up device disabled.
1 = All port P pins have an active pull-up device enabled.
