0b = VDS_OCP and SEN_OCP retry time is 4 ms 1b = VDS_OCP and SEN_OCP retry time is 50 µs |
| 9-8 | DEAD_TIME | R/W | 01b |
00b = 50-ns dead time 01b = 100-ns dead time 10b = 200-ns dead time 11b = 400-ns dead time |

00b = Overcurrent causes a latched fault 01b = Overcurrent causes an automatic retrying fault 10b = Overcurrent is report only but no action is taken 11b = Overcurrent is not reported and no action is taken |
| 5-4 | OCP_DEG | R/W | 01b |
00b = Overcurrent deglitch time of 2 µs 01b = Overcurrent deglitch time of 4 µs 10b = Overcurrent deglitch time of 6 µs 11b = Overcurrent deglitch time of 8 µs |
