PRODUCTION DATA
STATUS_INPUT is a standard PMBus? command that returns the status flags related to input voltage, current, and power as shown in Table 9-69.
This command uses the PMBus? read byte protocol.
To clear the bits in this register, the underlying faults must be removed and the CLEAR_FAULTS command must be issued by the host controller.
