*1
Active only when GPIO is set as input port.
*2
Active only when GPIO type is set as "Programmable GPIO" and set as output port.
*3
Default value depends on RXDEFSEL setting when Power on sequence. RXDEFSEL=1 → default value is 0 , RXDEFSEL=0 → default value is 1.
*4
Filter eliminates input glitch shorter than tOSC/2.
*5
GPIO input transition is counted as GPIO_INT(0x02 bit3).
