5.6 GPIO Settings
These settings detail the default configurations of the GPIO rails. All these settings can be changed though I
2
C
after startup. Note that the contents of the GPIOx_SEL field determine which other fields in the GPIOx_CONF
and GPIO_OUT_x registers are applicable. To understand which NVM fields apply to each GPIOx_SEL option,
see the Digital Signal Descriptions section in TPS6594-Q1 data sheet.
