Bit Field Type Reset Description
7-6 IO3 R/W X
Selects mode for AUXIO3 (for AIODIO0) or AUXIO11 (for AIODIO1).
0h = Output
1h = Digital input with GPIODIE bit 3 = 1 Analog input/output with
GPIODIE bit 3 = 0
2h = Open-drain: The pin is driven low when the corresponding
GPIODOUT bit is 0, and otherwise tri-stated or pulled depending on
the corresponding IOC configuration.
3h = Open-source: The pin is driven high when the corresponding
GPIODOUT bit is 1, and otherwise tri-stated or pulled depending on
the corresponding IOC configuration.
5-4 IO2 R/W X
Selects mode for AUXIO2 (for AIODIO0) or AUXIO10 (for AIODIO1).
0h = Output
1h = Digital input with GPIODIE bit 2 = 1 Analog input/output with
GPIODIE bit 2 = 0
2h = Open-drain: The pin is driven low when the corresponding
GPIODOUT bit is 0, and otherwise tri-stated or pulled depending on
the corresponding IOC configuration.
3h = Open-source: The pin is driven high when the corresponding
GPIODOUT bit is 1, and otherwise tri-stated or pulled depending on
the corresponding IOC configuration.
3-2 IO1 R/W X
Selects mode for AUXIO1 (for AIODIO0) or AUXIO9 (for AIODIO1).
0h = Output
1h = Digital input with GPIODIE bit 1 = 1 Analog input/output with
GPIODIE bit 1 = 0
2h = Open-drain: The pin is driven low when the corresponding
GPIODOUT bit is 0, and otherwise tri-stated or pulled depending on
the corresponding IOC configuration.
3h = Open-source: The pin is driven high when the corresponding
GPIODOUT bit is 1, and otherwise tri-stated or pulled depending on
the corresponding IOC configuration.
1-0 IO0 R/W X
Selects mode for AUXIO0 (for AIODIO0) or AUXIO8 (for AIODIO1).
0h = Output
1h = Digital input with GPIODIE bit 0 = 1 Analog input/output with
GPIODIE bit 0 = 0
2h = Open-drain: The pin is driven low when the corresponding
GPIODOUT bit is 0, and otherwise tri-stated or pulled depending on
the corresponding IOC configuration.
3h = Open-source: The pin is driven high when the corresponding
GPIODOUT bit is 1, and otherwise tri-stated or pulled depending on
the corresponding IOC configuration.
