GPIO interrupt request
When the GPIO is programmed as input pin, any transition in GPIO
pins (a recognizable logic state shall keep stable for at least two
debounce clocks (TCLK_BUN)) will set related bits in this register to
logical high. Besides, the GPIO module will not issue interrupt request
to CPU host unless the same bits of PIEN and PINT are both set high.
