|---|---|---|---|---|
| 7 | AREG_SELECT | R/W | 0h | The analog supply selection from either the internal regulator supply or the external AREG supply. 0d = External 1.8-V AREG supply (use this setting when AVDD is 1.8 V and short AREG with AVDD) 1d = Internally generated 1.8-V AREG supply using an on-chip regulator (use this setting when AVDD is 3.3 V) |
| 6-5 | Reserved | R/W | 0h | Reserved |
| 4-3 | VREF_QCHG[1:0] | R/W | 0h | The duration of the quick-charge for the VREF external capacitor is set using an internal series impedance of 200 Ω. 0d = VREF quick-charge duration of 3.5 ms (typical) 1d = VREF quick-charge duration of 10 ms (typical) 2d = VREF quick-charge duration of 50 ms (typical) 3d = VREF quick-charge duration of 100 ms (typical) |
| 2 | I2C_BRDCAST_EN | R/W | 0h | I2C broadcast addressing setting. 0d = I2C broadcast mode disabled; the I2C target address is determined based on the ADDR pins 1d = I2C broadcast mode enabled; the I2C target address is fixed at 1001 100 |
| 1 | Reserved | R | 0h | Reserved |
| 0 | SLEEP_ENZ | R/W | 0h | Sleep mode setting. 0d = Device is in sleep mode 1d = Device is not in sleep mode |
