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. Table 21 describes the STATUS_WORD message content.
The STATUS_VOUT command returns 1 byte of information with contents as described in Table 22.
Table_22._STATUS_VOUT
The STATUS_CML command returns 1 byte of information with contents as described in Table 23.
