GPIO Subsystem Register Descriptions
6.16.2.6 GPIO Output Auxiliary 2 Select (GPIO[x]_OUT_AUX2_SEL)
These registers select the Auxiliary 2 output of the low (GPIO[15:0]) and high (GPIO[31:16]) banks of GPIOs. Auxiliary 2 is
selected as the output if the feature bit is high. Auxiliary 2 is not selected as the output if the feature bit is low. (These regis-
ters use atomic programming, see Section 6.16.1 on page 454 for details.)
If OUT_AUX1 and/or OUT_AUX2 are selected, then their value overrides the OUT_VAL (GPIO I/O Offset 00h/80h) set-
tings. See Table 3-8 "GPIO Options" on page 47 for AUX programming details.

6.16.2.7 GPIO/AUX Pull-Up Enable (GPIO[x]_PU_EN)
These registers control enabling of the pull-up on the low (GPIO[15:0]) and high (GPIO[31:16]) banks of GPIOs. If the fea-
ture bit is high, the pull-up is enabled. If the feature bit is low, the pull-up is disabled. The reset value forces all the pull-ups
to be disabled. (These registers use atomic programming, see Section 6.16.1 on page 454 for details.)
