GPIO5 Event Status
Bit 7-0 corresponds to GP57-GP50, 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.
GPIO3 I/O register
0: The respective GPIO3 PIN is programmed as an output port
1: The respective GPIO3 PIN is programmed as an input port.
GPIO3 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.
GPIO3 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)
Select Suspend LED mode.
00: Suspend LED pin is tri-stated.
01: Suspend LED pin is driven low.
10: Suspend LED pin outputs 1Hz pulse with 50% duty cycle.
11: Suspend LED pin outputs 0.25Hz pulse with 50% duty cycle.
