The status of the Current Limit Switch 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 LS_FAULT bit

described in Table 95 selects whether the Limit Switch contributes to the /VCC_FAULT indication.

When LS_FAULT = 0, then an overcurrent condition on the Limit Switch will cause the /VCC_FAULT

output to be set to logic low.
