ADCOption Register (I2C address = 3B/3Ah) [reset = 2000h] 7 6 5 4-0 ADC_CONV ADC_START ADC_ FULLSCALE Reserved R/W R/W R/W R/W 7 6 5 4 3 2 1 0 EN_ADC_ CMPIN EN_ADC_ VBUS EN_ADC_ PSYS EN_ADC_ IIN EN_ADC_ IDCHG EN_ADC_ ICHG EN_ADC_ VSYS EN_ADC_ VBAT R/W R/W R/W R/W R/W R/W R/W R/W LEGEND: R/W = Read/Write; R = Read only; -n = value after reset 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. Table 9-17. ADCOption Register (I2C address = 3Bh) Field Descriptions I2C 3Bh FIELD TYPE RESET DESCRIPTION 7 ADC_CONV R/W 0b Typical ADC conversion time is 10 ms. 0b: One-shot update. Do one set of conversion updates to registers REG0x27/26(), REG0x29/28(), REG0x2B/2A(), and REG0x2D/2C() after ADC_START = 1. 1b: Continuous update. Do a set of conversion updates to registers REG0x27/26(), REG0x29/28(), REG0x2B/2A(), and REG0x2D/2C() every 1 sec. 6 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 5 ADC_ FULLSCALE R/W 1b 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> 4-0 Reserved R/W 00000b Reserved Table 9-18.
