The STATUS_VOUT command returns one data byte with contents as follows. All supported bits can be cleared either by CLEAR_FAULTS, or individually by writing 1b to the (7Ah) STATUS_VOUT register in their position, per the PMBus 1.3.1 Part II specification section 10.2.4.

| LEGEND: R/W = Read/Write; R = Read only |
| Bit | Field | Access | Reset | Description |
|---|---|---|---|---|
| 7 | VOUT_ OVF | RW | 0b | 0b: Latched flag indicating VOUT OV fault has NOT occurred. 1b: Latched flag indicating a VOUT OV fault has occurred. Note: the mask bits for VOUT_ OVF will mask fixed, tracking, and pre-biased OVP. These can be individually controlled in SMBALERT_ MASK_ EXTENDED. |
| 6 | VOUT_ OVW | RW | 0b | 0b: Latched flag indicating VOUT OV warn has NOT occurred. 1b: Latched flag indicating a VOUT OV warn has occurred. Note: the mask bits for VOUT_ OVF will mask fixed and tracking Overvoltage Protection. |
| 5 | VOUT_ UVW | RW | 0b | 0b: Latched flag indicating VOUT UV warn has NOT occurred. 1b: Latched flag indicating a VOUT UV warn has occurred. |
| 4 | VOUT_ UVF | RW | 0b | 0b: Latched flag indicating VOUT UV fault has NOT occurred. 1b: Latched flag indicating a VOUT UV fault has occurred. |
| 3 | VOUT_ MIN_MAX | RW | 0b | 0b: Latched flag indicating a VOUT_ MIN_MAX has NOT occurred. 1b: Latched flag indicating a VOUT_ MIN_MAX has occurred. |
| 2 | TON_ MAX | RW | 0b | 0b: Latched flag indicating a TON_ MAX has NOT occurred. 1b: Latched flag indicating a TON_ MAX has occurred. |
| 1:0 | Not supported | R | 00b | Not supported and always set to 00b. |
All bits which can trigger SMBALERT have a corresponding bit in SMBALERT_MASK.
