PRODUCTION DATA
All the status bits in REG0x23[7,2],REG0x23[6:0] will be cleared after host read.

| LEGEND: R/W = Read/Write; R = Read only; -n = value after reset |
| BIT | FIELD | TYPE | RESET | DESCRIPTION |
|---|---|---|---|---|
| 7 | Reserved | R | 1b | Reserved |
| 6 | EN_PROCHOT _EXT | R/W | 0b | PROCHOT Pulse Extension Enable. When pulse extension is enabled, keep the PROCHOT pin voltage LOW until host writes PROCHOT _CLEAR = 0b. 0b: Disable pulse extension <default at POR> 1b: Enable pulse extension |
| 5-4 | PROCHOT _WIDTH | R/W | 11b | PROCHOT Pulse Width Minimum PROCHOT pulse width when EN_PROCHOT _EXT = 0b 00b: 100 us 01b: 1 ms 10b: 5 ms 11b: 10 ms <default at POR> |
| 3 | PROCHOT _CLEAR | R/W | 1b | PROCHOT Pulse Clear. Clear PROCHOT pulse when EN_PROCHOT _EXT = 1b. 0b: Clear PROCHOT pulse and drive PROCHOT pin HIGH 1b: Idle <default at POR> |
| 2 | TSHUT | R | 0b | TSHUT trigger: 0b: TSHUT is not triggered 1b: TSHUT is triggered |
| 1 | STAT_VAP_FAIL | R/W | 0b | This status bit reports a failure to load VBUS 7 consecutive times in VAP mode, which indicates the battery voltage might be not high enough to enter VAP mode, or the VAP loading current settings are too high. 0b: Not is VAP failure <default at POR> 1b: In VAP failure, the charger exits VAP mode, and latches off until the host writes this bit to 0. |
| 0 | STAT_EXIT_VAP | R/W | 0b | When the charger is operated in VAP mode, it can exit VAP by either being disabled through host, or there are ACOV/ACOC/SYSOVP/BATOVP/VSYS_UVP faults. 0b: PROCHOT_EXIT_VAP is not active <default at POR> 1b: PROCHOT_EXIT_VAP is active, PROCHOT pin is low until host writes this status bit to 0. |
| BIT | FIELD | TYPE | RESET | DESCRIPTION |
|---|---|---|---|---|
| 7 | STAT_VINDPM | R/W | 0b | PROCHOT Profile VINDPM status bit 0b: Not triggered 1b: Triggered, PROCHOT pin is low until host writes this status bit to 0 when PP_VINDPM = 1b |
| 6 | STAT_COMP | R | 0b | PROCHOT Profile CMPOUT status bit. The status is latched until a read from host. 0b: Not triggered 1b: Triggered |
| 5 | STAT_ICRIT | R | 0b | PROCHOT Profile ICRIT status bit. The status is latched until a read from host. 0b: Not triggered 1b: Triggered |
| 4 | STAT_INOM | R | 0b | PROCHOT Profile INOM status bit. The status is latched until a read from host. 0b: Not triggered 1b: Triggered |
| 3 | STAT_IDCHG1 | R | 0b | PROCHOT Profile IDCHG1 status bit. The status is latched until a read from host. 0b: Not triggered 1b: Triggered |
| 2 | STAT_VSYS | R | 0b | PROCHOT Profile VSYS status bit. The status is latched until a read from host. 0b: Not triggered 1b: Triggered |
| 1 | STAT_Battery_Removal | R | 0b | PROCHOT Profile Battery Removal status bit. The status is latched until a read from host. 0b: Not triggered 1b: Triggered |
| 0 | STAT_Adapter_Removal | R | 0b | PROCHOT Profile Adapter Removal status bit. The status is latched until a read from host. 0b: Not triggered 1b: Triggered |
