| 7 | Fault ACOV | R | 0b |
The faults are latched until a read from host. 0b: No fault 1b: ACOV |
| 6 | Fault BATOC | R | 0b |
The faults are latched until a read from host. 0b: No fault 1b: BATOC |
| 5 | Fault ACOC | R | 0b |
The faults are latched until a read from host. 0b: No fault 1b: ACOC |
| 4 | SYSOVP_STAT | R | 0b |
SYSOVP Status and Clear When the SYSOVP occurs, this bit is HIGH. During the SYSOVP, the converter is disabled. After the SYSOVP is removed, the user must write a 0 to this bit or unplug the adapter to clear the SYSOVP condition to enable the converter again. 0b: Not in SYSOVP <default at POR> 1b: In SYSOVP. When SYSOVP is removed, write 0 to clear the SYSOVP latch. |
