PRODUCTION DATA
| CMD Address | 7Fh |
| Write Transaction: | Write Byte |
| Read Transaction: | Read Byte |

The STATUS_OTHER command returns one data byte with information not specified in the other STATUS bytes.
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| R | R | R | R | R | R | R | RW |
| 0 | 0 | 0 | 0 | 0 | 0 | 0 | FIRST_ TO_ALERT |
| LEGEND: R/W = Read/Write; R = Read only |
| Bit | Field | Access | Reset | Description |
|---|---|---|---|---|
| 7:1 | Reserved | R | 0h | Reserved |
| 0 | FIRST_ TO_ ALERT | RW | 0b | 0b: Latched flag indicating that this device was NOT the first to assert
SMBALERT. This can mean either that the SMBALERT signal is not
asserted (or has since been cleared), or that it is asserted, but
this device was not the first on the bus to assert it. 1b: Latched flag indicating that this device was the first to assert SMBALERT. |
The corresponding bit STATUS_BYTE is an OR’ing of the supported bits in this command. When a fault condition in this command occurs, the corresponding bit in STATUS_BYTE is updated. Likewise, if this byte is individually cleared (for example, by a write of 1 to a latched condition), it must clear the corresponding bit in STATUS_BYTE.
