(1) Note that this NVM default value can change when the device transitions to ACTIVE mode.
4.5 VCCA and VMON Settings
These settings detail the default monitoring enabled on VCCA. All these settings can be changed though I

4.6 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: 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 TPS6593-Q1 datasheet.
