Active only when GPIO is set as input port.
Active only when GPIO type is set as "Programmable GPIO" and set as output port.
Default value depends on RXDEFSEL setting when Power on sequence. RXDEFSEL=1 → default value is 0 , RXDEFSEL=0 → default value is 1.
Filter eliminates input glitch shorter than tOSC/2.
GPIO input transition is counted as GPIO_INT(0x02 bit3).
