The ADC registers are read in the following order: VBAT, VSYS, ICHG, IDCHG, IIN, PSYS, VBUS, CMPIN. ADC is disabled in low power mode. When enabling ADC, the device exit low power mode at battery only.

FIELD | TYPE | RESET | DESCRIPTION |
---|---|---|---|---|
15 | ADC_CONV | R/W | 0b | Typical ADC conversion time is 10 ms.
0b: One-shot update. Do one set of conversion updates to registers REG0x23(), REG0x24(), REG0x25(), and REG0x26() after ADC_START = 1. 1b: Continuous update. Do a set of conversion updates to registers REG0x23(), REG0x24(), REG0x25(), and REG0x26() every 1 sec. |
14 | ADC_START | R/W | 0b |
0b: No ADC conversion 1b: Start ADC conversion. After the one-shot update is complete, this bit automatically resets to zero |

ADC input voltage range. When input voltage is below 5 V, or battery is 1S, full scale 2.04 V is recommended. 0b: 2.04 V 1b: 3.06 V <default at POR> |
