I am trying to generate a GPT interrupt as fast as possible, using the example code, the GPT clock source is 62.5MHz but I can only get an interrupt every 1us (not exactly as comparison count is 62 or 63 . If I specify a smaller compare value, the interrupt didn't seem to be triggering. Does anyone know if there is a limitation here?
Can it be possible to use a high speed internal clock, I have tried to change to the high frequency clock without seeing a difference. I might be missing some synchronization or something while trying to enable it.
I will appreciate any help,
Thanks,
