GPIO2 I/O register
0: The respective GPIO2 PIN is programmed as an Output port
1: The respective GPIO2 PIN is programmed as an Input port.
GPIO2 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.
GPIO2 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)
GPIO2 Event Status
Bit 4-0 corresponds to GP24-GP20, 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.
Select Suspend LED mode.
00: Suspend LED pin is driven low.
01: Suspend LED pin is tri-stated.
10: Suspend LED pin outputs 1Hz pulse with 50% duty cycle.
11: Suspend LED pin outputs
