Center-Aligned PWM
Center-aligned PWM signals are produced by the mod-
ule when the PWM time base is configured in an
Up/Down Counting mode (see Figure 15-3).
The PWM compare output is driven to the active state
when the value of the duty cycle register matches the
value of PTMR and the PWM time base is counting
downwards (PTDIR = 1). The PWM compare output is
driven to the inactive state when the PWM time base is
counting upwards (PTDIR = 0) and the value in the
PTMR register matches the duty cycle value.
If the value in a particular duty cycle register is zero,
then the output on the corresponding PWM pin will be
inactive for the entire PWM period. In addition, the out-
put on the PWM pin will be active for the entire PWM
period if the value in the duty cycle register is equal to
the value held in the PTPER register.

PWM Duty Cycle Comparison
Units
There are four 16-bit special function registers (PDC1,
PDC2, PDC3 and PDC4) used to specify duty cycle
values for the PWM module.
The value in each duty cycle register determines the
amount of time that the PWM output is in the active
state. The duty cycle registers are 16 bits wide. The
LSb of a duty cycle register determines whether the
PWM edge occurs in the beginning. Thus, the PWM
resolution is effectively doubled.
15.5.1
DUTY CYCLE REGISTER BUFFERS
The four PWM duty cycle registers are double-buffered
to allow glitchless updates of the PWM outputs. For
each duty cycle, there is a duty cycle register that is
accessible by the user and a second duty cycle register
that holds the actual compare value used in the present
PWM period.
For edge-aligned PWM output, a new duty cycle value
will be updated whenever a match with the PTPER reg-
ister occurs and PTMR is reset. The contents of the
duty cycle buffers are automatically loaded into the
duty cycle registers when the PWM time base is dis-
abled (PTEN = 0) and the UDIS bit is cleared in
PWMCON2.
When the PWM time base is in the Up/Down Counting
mode, new duty cycle values are updated when the
value of the PTMR register is zero and the PWM time
base begins to count upwards. The contents of the duty
cycle buffers are automatically loaded into the duty
cycle registers when the PWM time base is disabled
(PTEN = 0).
When the PWM time base is in the Up/Down Counting
mode with double updates, new duty cycle values are
updated when the value of the PTMR register is zero,
and when the value of the PTMR register matches the
value in the PTPER register. The contents of the duty
cycle buffers are automatically loaded into the duty
cycle registers when the PWM time base is disabled
(PTEN = 0).
