Hi
If you look on page 129 of the data sheet. There is a chart of Fosc vs. PWM frequency.
They do not list 8mhz, but the highest 4mhz frequency is 3.9khz. So I guess you can expect
it to be double at 8mhz or 7.8Khz
If you configure the oscillator for 4x HSPLL you could get closer.
8mhz crystal 4x HSPLL - PWM freq = 31.2khz max
Did the PWM output anything, you didn't say?
