6.16.2
6.16.2.1 GPIO Output Value (GPIO[x]_OUT_VAL)
These registers control the output value for the low (GPIO[15:0]) and high (GPIO[31:16]) banks of GPIOs. If the feature bit
is high, the output value = 1. If the feature bit is low, the output value = 0. The reset value forces all the output values to be
initially set to 0. (These registers use atomic programming, see Section 6.16.1 on page 454 for details.)
If OUT_AUX1 (GPIO I/O Offset 10h/90h) and/or OUT_AUX2 (GPIO I/O Offset 14h/94h) are selected, then their value over-
rides the OUT_VAL settings. See Table 3-8 "GPIO Options" on page 47 for AUX programming details.

6.16.2.2 GPIO/OUT_AUX Output Enable (GPIO[x]_OUT_EN)
These registers control the output enable for the low (GPIO[15:0]) and high (GPIO[31:16]) banks of GPIOs. If the feature bit
high, the output is enabled. If the feature bit is low, the output is disabled. The reset value forces all the outputs to be dis-
abled. (These registers use atomic programming, see Section 6.16.1 on page 454 for details.)
