Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

From the manual 2019-06-25_212755:

  Quote  
Eight PWM Channels
Minimum frequency is 1Hz, maximum is 24MHz. Duty cycle and frequency accuracy will depend on
frequency. The frequency can be any value of 240,000,000/n.


This has recently changed from 200,000,000 (from 400MHz to 480MHz?)

Would this be, say 270,000,000 for 540MHz, etc.? (figuring out PWM-DAC resolution).

If this is the case, might be better worded as nominal CPU freq/2 (?)
