GPIO2 Data register
For output ports, the respective bits can be read and written by the pins.
For input ports, the respective bits can only be read by the pins. Write
accesses are ignored.
GPIO2 Inversion register
0: The respective bit and the port value are the same.
1: The respective bit and the port value are inverted. (Applies to both input
and output ports)
GPIO2 Event Status
Bit 7-0 corresponds to GP27-GP20, respectively.
0 : No active edge(rising/falling) has been detected
1 : An active edge(rising/falling) has been detected
Read the status bit clears it to 0.
GPIO3 Event Status
Bit 7-0 corresponds to GP37-GP30, respectively.
0 : No active edge(rising/falling) has been detected
1 : An active edge(rising/falling) has been detected
Read the status bit clears it to 0.
GPIO4 Event Status
Bit 7-0 corresponds to GP47-GP40, respectively.
0 : No active edge(rising/falling) has been detected
1 : An active edge(rising/falling) has been detected
Reading the status bit clears it to 0.
