GPIO Subsystem Register Descriptions (Continued)

5.16.2.3

GPIO 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 5.16.1 on

page 436 for details.)

GPIO Low Bank Output Open-Drain Enable

(GPIOL_OUT_OD_EN)

GPIO High Bank Output Open-Drain Enable

(GPIOH_OUT_OD_EN)

5.16.2.4

GPIO 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 5.16.1 on page 436 for details.)
