Active only when GPIO is set as input port.

Note that GPIO2_INPUT_MONITOR corresponds to Bit#”0”, GPIO0_INPUT_MONITOR corresponds to Bit#”2”.

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.

Note that GPIO2_FILT_ENABLE corresponds to Bit#”0”, GPIO0_FILT_ENABLE corresponds to Bit#”2”.
