I was just wondering, whats the difference between
"pwm_interrupt_update_channel" and "pwm_update_channel".
I am running a PWM at 1MHz and I can update its frequency and/or duty-cycle to another value with either one of these functions.
But in BOTH cases I cannot read back the correct new value from .cprd right after the update-function returns.
So what for is the polling method then?
And what for is the interrupt method then?
