17.4.2
When the PWM time base is in the Single-shot mode
(PTMOD<1:0> = 01), an interrupt event is generated
when a match with the PTPER register occurs. The
PWM timer register (PTMR) is reset to zero on the
following input clock edge, and the PTEN bit is cleared.
The postscaler selection bits have no effect in this
Timer mode.

In the Up/Down Counting mode (PTMOD<1:0> = 10),
an interrupt event is generated each time the value of
the PTMR register becomes zero and the PWM time
base begins to count upwards. The postscaler
selection bits may be used in this mode of the timer to
reduce the frequency of the interrupt events.
Figure 17-7 shows the interrupts in continuous
Up/Down Counting mode.
