GPIO/XGPIO timing characteristics
For edge-sensitive signals, the interrupt line is sampled by flip flops clocked by PCLK for
GPIOs and HCLK for XGPIOs, the APB and AHB clocks, normally running at 83 MHz and
166 MHz respectively.
The minimum pulse width required for interrupt detection on signal edge is:
3*TPCLK (36 ns at 83 MHz) for GPIO
3*THCLK (18 ns at 166 MHz) for XGPIO
