8.3.14.7.1.12 STATUS_WORD (79h, Read Word)

STATUS_WORD is a standard PMBus® command that returns two bytes of information with a summary of the eFuse fault conditions.

This command uses the PMBus® read word 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.

The low byte of STATUS_WORD is the same register as the STATUS_BYTE command. The STATUS_WORD register contents are described in Figure 8-18 and Table 9-69.

Figure 8-18 Status Register Bit Map.

Table 8-11 STATUS_WORD Register Description

Bit	Name	Value	Description	Default	Access
15	OUT_STATUS		OUTPUT fault status		Read
		1	Active bits set in the STATUS_OUT register	0
		0	No active bits set in the STATUS_OUT register	0
14	IOUT_STATUS		IOUT fault status
		1	Active bits set in the STATUS_IOUT register	0
		0	No active bits set in the STATUS_IOUT register	0
13	INPUT_STATUS		INPUT fault status
		1	Active bits set in the STATUS_INPUT register	0
		0	No active bits set in the STATUS_INPUT register	0
12	MFR_STATUS		Manufacturer specific fault status
		1	Active bits set in the STATUS _MFR_SPECIFIC register	0
		0	No active bits set in the STATUS _MFR_SPECIFIC register	0
11	PGOODB		Power Good status
		1	PGOOD de-asserted	1
		0	PGOOD asserted	1
10:9	Reserved	00	Reserved	00
8	UNKNOWN	1	An event other than the ones listed in bits 15:1 has occurred	0
8	UNKNOWN	0	An event other than the ones listed in bits 15:1 has not occurred	0
7:0	Same as STATUS_BYTE register

Figure 8-19 depicts the relationship between the STATUS_BYTE register, the STATUS_WORD register and the more detailed status registers.

Based on the information in these bytes, the host can get more insight by reading the appropriate status registers.
