-200- Version 1.4
CR E9h. (GPIO5 Status Register; Default 00h)
BIT READ / WRITE DESCRIPTION
7
Read Only
Read-Clear
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.
CR F0h. (GPIO3 I/O Register; Default FFh)
BIT READ / WRITE DESCRIPTION
7~0 R / W
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.
CR F1h. (GPIO3 Data Register; Default 00h)
BIT READ / WRITE DESCRIPTION
R / W
GPIO3 Data register
For output ports, the respective bits can be read and written by the pins.
7~0
Read Only
For input ports, the respective bits can only be read by the pins. Write
accesses are ignored.
CR F2h. (GPIO3 Inversion Register; Default 00h)
BIT READ / WRITE DESCRIPTION
7~0 R / W
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)
CR F3h. (Suspend LED Mode Register; Default 00h) (VBAT power)
