Hello everybody.
I'm working on a Keil MCB4300 board with a LPC4357, and I've encounter a problem with the GPIO frequency. My program use two timers with interrupt to set and clear two GPIO, but the shortest time between the set and the clear is 120 ns (8,3 MHz). I use the PLL1 at 204 MHz for all the base clocks, so I would like to know if and how I can reduce the time min between the set and the clear.
It's using the full PLL, for the source clock you can choose the PLL or different clock divided from the PLL, and I choose the PLL.
