GPIO Subsystem Register Descriptions
6.16.2.3 GPIO/OUT_AUX Output Open-Drain Enable (GPIO[x]_OUT_OD_EN)
These registers control the open-drain enable of the output for the low (GPIO[15:0]) and high (GPIO[31:16]) banks of
GPIOs. The open-drain is enabled if the feature bit is high. The open-drain is disabled if the feature bit is low.The reset
value forces all open-drains on the outputs to be disabled. (These registers use atomic programming, see Section 6.16.1
on page 454 for details.)

6.16.2.4 GPIO/OUT_AUX Output Invert Enable (GPIO[x]_OUT_INVRT_EN)
These registers control the output invert enable for the low (GPIO[15:0]) and high (GPIO[31:16]) banks of GPIOs. The out-
put is inverted if the feature bit is high. The output is not inverted if the feature bit is low. (These registers use atomic pro-
gramming, see Section 6.16.1 on page 454 for details.)
