FIGURE 17-14:

Center-aligned PWM signals are produced by the
module when the PWM time base is configured in a
Continuous Up/Down Count mode (see Figure 17-15).
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
will be 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

output on the PWM pin will be active for the entire PWM
period if the value in the Duty Cycle register is equal to
or greater than the value in the PTPER register.

When
Center-Aligned mode, the PWM Time
Base Period register (PTPER) is loaded
into the PWM Time Base register (PTMR)
and the PTMR is configured automatically
to start down counting. This is done to
ensure that all the PWM signals don’t start
at the same time.
