GPIO Subsystem Register Descriptions
5.16.2.5
These registers select the Auxiliary 1 output of the low (GPIO[15:0]) and high (GPIO[31:16]) banks of GPIOs. Auxiliary 1 is
selected as the output if the feature bit is high. Auxiliary 1 is not selected as the output if the feature bit is low. (These regis-
ters use atomic programming, see Section 5.16.1 on page 436 for details.)
If OUT_AUX1 and/or OUT_AUX2 are selected, then their value overrides the OUT_VAL (GPIO I/O Offset 00h/80h) settings.
See Table 2-8 "GPIO Options" on page 42 for AUX programming details.
