Value Description
VCCA_VMON_CTRL VMON_DEGLITCH_SEL 0x1 20 us
VCCA_VMON_EN 0x1 Enabled; OV and UV comparators.
VCCA_PG_WINDOW VCCA_OV_THR 0x7 +10%

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.
