0: GPIO2 is inactive.
0: GPIO1 is inactive.
GPIO1 I/O register
0: The respective GPIO1 PIN is programmed as an Output port
1: The respective GPIO1 PIN is programmed as an Input port.
GPIO1 Data register
For Output ports, the respective bits can be read and written by the pins.
For Input ports, the respective bits can be read only from pins. Write
accesses will be ignored.
GPIO1 Inversion register
0: The respective bit and the port value are the same.
1: The respective bit and the port value are inverted. (Both Input & Output
ports)
GPIO1 Event Status
Bits 7-0 correspond to GP17-GP10, 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.
