Description
Default R/W
15:14
VS[2:1] Direction.
0 – Input
1 – Output
Input pull–up resistors are weak. During Standby mode the pull–up resistors are disabled.

R/W
11
GPIO Direction.
See Note.
0 – Input
1 – Output
0
R/W
10
GPIO Output Value When Card Power Enable Bit is Low.
See Note.
0
R/W
9
GPIO Output Value When Card Power Enable Bit is High.
See Note.
0
R/W
8:6
PCTL[2:0] Direction.
0 – Input
1 – Output
00
R/W
5:3
PCTL[2:0] Output Value When Card Power Enable Bit is Low.
PCTL[0] is a tristate output
only. PCTL[2:1] are bidirectional. The PCTL[2:1] input value is at the Interrupt Pins register
and can generate an interrupt while PCTL[0] cannot generate an interrupt.
