Where exactly are you seeing this? Virtually nothing on the chip but
the A
I guess I would argue that with 16 bits the counter can count up to 65535 and
wrap around after 65536 counts of 128ns max. That gives a max period of the PWM
of 8.39ms and a min frequency of 119Hz - I think. But it has been a long day,
so I might very well be very wrong ;-)

According to the TRM, the Time Base module on each of the PWM subsystems is
clocked directly from the cpu clock. That is, its being clocked at a period of
1 nsec. It can be prescaled down to 1/128,for a period of 128 nsecs. The period
and the counter compare registers are only 16 bits wide so th
