ADVANCE INFORMATION
| CMD Address: | 7Dh |
| Write Transaction: | Write Byte |
| Read Transaction: | Read Byte |
| Format: | Unsigned Binary (1 byte) |
| NVM Back-up: | Yes |
| Updates: | On-the-fly |
The STATUS_TEMPERATURE command returns one data byte with contents as follows. All supported bits may be cleared either by CLEAR_FAULTS, turning on the output through the mechanism programmed into ON_OFF_CONFIG, or individually by writing 1b to the STATUS_TEMPERATURE register in their position, per the PMBus 1.3.1 Part II specification section 10.2.3.
None of these bits is affected by the state of SMBALERT_MASK. However, if the corresponding fault/warning disable bits in the FAULT_CTRL register is set, then the corresponding status bits will also be blocked in addition to blocking the response from that fault.
Return to Supported PMBus Commands.
