I'm looking at the 120MHZ ATSAME51J20A for a potentially new design.
I need to create custom waveform outputs on the GPIO and I'm wondering what sort of repeatable accuracy can I hope to get. For example, if I was producing a 1us square wave, how accurate and consistent would edges be? So every 500ns, the code would toggle the GPIO pin, how accurate would the pulse width be? +-25ns, 50ns, 100ns.... etc. Its just an example, Its a more complicated wave shape.
Since the GPIO are on the other side of the various bridges, and there are other peripherals there, I'm not sure what to expect.
