Description
VS[2:1] Direction.
0 – Input
1 – Output
Input pull–up resistors are weak. During Standby mode the pull–up resistors are disabled.
VS[2:1] Output Value.
GPIO Direction. See Note.
0 – Input
1 – Output
GPIO Output Value When Card Power Enable Bit is Low. See Note.
GPIO Output Value When Card Power Enable Bit is High. See Note.
PCTL[2:0] Direction.
0 – Input
1 – Output
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.
PCTL[2:0] Output Value When Card Power Enable Bit is High.
