18.4.2
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 Time Base 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.

Note 1: Interrupt flag bit, PTIF, is sampled here (every Q1).
A: PRESCALER = 1:1
B: PRESCALER = 1:4
2: PWM Time Base Period register, PTPER, is loaded with the value, FFFh, for this example.

In
(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.
