Hello,
I am wondering what the possible PWM frequencies are on the Teensy 4.1. I am hoping to use 50% duty-cycled PWM or some other hardware timer based method (ideally no load on the CPU) to generate a 1.0MHz clock for an external ADC. On the teensy website https://www.pjrc.com/teensy/td_pulse.html there is a table of frequencies and the corresponding resolution, but are those *all* the available frequencies? Internally, is there some clock divider / PLL doing the work to generate them, and what are the available divider ratios?
If others have alternative suggestions for how to generate a 1.0MHz clock on any output pin (I have flexibility), I'm certainly open to those.
