The status of the DC-DC Converters can be indicated and monitored externally via a GPIO pin
configured as /VCC_FAULT (see Section 20). When a GPIO pin is configured as /VCC_FAULT
output, a logic low level on this pin indicates that there is a fault condition on one of the LDO
Regulators, DC-DC Converters, or the Current Limit switch.
The /VCC_FAULT output is configurable by the control fields in Register R215. The fields described
in Table 80 determine which of the DC-DCs contribute to the /VCC_FAULT indication. An
undervoltage or overvoltage condition on any unmasked DC-DC Converter will cause the
/VCC_FAULT output to be set to logic low.
