Is the fastest timer interrupt I can achieve one millisecond?  I'm running default clocks.  System clock is 403.2 MHz.

The maximum frequency you can feed the complex GPIO is SYS_CLK/2 so it is around 200MHz and say you keep a threshold value of 1 while configuring the complex GPIO it should half the value. so theoretically it would be 100MHz but at that speed if you trigger the interrupt I doubt you'll be able to execute anything.

What is the frequency you're looking at for your application?
