Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Selects mode for AUXIO7 (for AIODIO0) or AUXIO15 (for AIODIO1).
0h = Output
1h = Digital input with GPIODIE bit 7 = 1
Analog input/output with GPIODIE bit 7 = 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.
Selects mode for AUXIO6 (for AIODIO0) or AUXIO14 (for AIODIO1).
0h = Output
1h = Digital input with GPIODIE bit 6 = 1
Analog input/output with GPIODIE bit 6 = 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.
Selects mode for AUXIO5 (for AIODIO0) or AUXIO13 (for AIODIO1).
0h = Output
1h = Digital input with GPIODIE bit 5 = 1
Analog input/output with GPIODIE bit 5 = 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.
Selects mode for AUXIO4 (for AIODIO0) or AUXIO12 (for AIODIO1).
0h = Output
1h = Digital input with GPIODIE bit 4 = 1
Analog input/output with GPIODIE bit 4 = 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.
