| Bit | Field | Type | Reset | Description |
|---|---|---|---|---|
| 3 | COLDOFF | R/W | 0 | Set by PMIC cleared by host. Host to write 1b to clear. 0: Cleared 1: N/A. Not enabled for existing OTPs. |
| 2 | UVLO | R/W | 0 | Set by PMIC cleared by host. Host to write 1b to clear. 0: Cleared 1: PMIC was shut down due to a UVLO event (VSYS crosses below 5.4 V). Assertion of this bit sets the SHUTDN bit in Section 6.11.4. |
| 1 | PWR_FAULT | R/W | 0 | Set by PMIC cleared by host. Host to write 1b to clear. 0: Cleared 1: PMIC was shut down due to an unmasked power fault event. Assertion of this bit sets the SHUTDN bit in Section 6.11.4. The source of the power fault can be determined from the PWR_FAULT registers (0xB2 and 0xB3). Overcurrent protection limits IOUT and typically causes power fault as VOUT droops. |
| 0 | CRITTEMP | R/W | 0 | Set by PMIC cleared by host. Host to write 1b to clear. 0: Cleared 1: PMIC was shut down due to the rise of PMIC die temperature above critical temperature threshold (TCRIT). Assertion of this bit sets the SHUTDN bit in Section 6.11.4. |
