Table 10. STATUS_BYTE
The STATUS_WORD command returns 2 bytes of information with a summary of the reason for a fault. The low byte of
the STATUS_WORD is the same data as the STATUS_BYTE.
The STATUS_VOUT command returns 1 byte of information with contents as described in
Table 12. STATUS_VOUT
Maxim Integrated
The STATUS_BYTE command returns 1 byte of information with a summary of the most critical faults. A value of 1
indicates that a fault or warning event has occurred and a 0 indicates otherwise. Bits for unsupported features are
reported as 0. The STATUS_BYTE cannot be restored by RESTORE_DEFAULT_ALL command.
STATUS_BYTE message content. This command is read-only.
