PRODUCTION DATA
The STATUS_BYTE command is a read-only command. Write mask is not supported. The bits are listed in Table 8-12.
| PAGE SUPPORT | BIT | NAME | READ / WRITE | DEFAULT VALUE | MEANING |
|---|---|---|---|---|---|
| — | 7 | Not supported | R | 0 | — |
| Yes | 6 | OFF | R | — | Output is off |
| Yes | 5 | VOUT_OV | R | — | Output overvoltage fault |
| Yes | 4 | IOUT_OC | R | — | Output overcurrent fault |
| No | 2 | TEMPERATURE | R | — | Overtemperature fault |
| — | 3 | Not supported | R | 0 | — |
| No | 1 | CML | R | — | Invalid command code, data, or packet |
| Yes | 0 | NONE OF THE ABOVE | R | — | A fault or warning not listed in bits [7:1] has occurred |
Overtemperature fault and CML is independent of PAGE. When there is PAGE support, the meaning of the bits applies only for the selected output PAGE. For PAGE = 0xFF, STATUS_BYTE is a logical OR of all PAGE = 0x00 to 0x03 STATUS_BYTE values.
An exception to NONE OF THE ABOVE is that the MFR bit in STATUS_WORD is ignored due to no PAGE support.
PAGE support is for outputs 0x00 to 0x03, 0x0FF.
