Valid when VSEL is driven high. See the Output Voltage Programming section for more information. REG2 0x32 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG2 0x32 [6] PHASE R/W Regulator Phase Control. Set bit to 1 for the regulator to operate 180° out of phase with the oscillator, clear bit to 0 for the regulator to operate in phase with the oscillator. REG2 0x32 [5] MODE R/W Regulator Mode Select. Set bit to 1 for fixed-frequency PWM under all load conditions, clear bit to 0 to transit to power- savings mode under light-load conditions. REG2 0x32 [4:2] DELAY R/W Regulator Turn-On Delay Control. See the REG1, REG2, REG3 Turn-on Delay section for more information. REG2 0x32 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault- interrupts, clear bit to 0 to disable fault-interrupts. REG2 0x32 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG3 0x40 [5:0] VSET1 R/W Primary Output Voltage Selection. Valid when VSEL is driven low. See the Output Voltage Programming section for more information. REG3 0x41 [7:6] - R Reserved. REG3 0x41 [5:0] VSET2 R/W Secondary Output Voltage Selection. Valid when VSEL is driven high. See the Output Voltage Programming section for more information. REG3 0x42 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG3 0x42 [6] - R/W Reserved. REG3 0x42 [5] MODE R/W Regulator Mode Select. Set bit to 1 for fixed-frequency PWM under all load conditions, clear bit to 0 to transit to power- savings mode under light-load conditions. REG3 0x42 [4:2] DELAY R/W Regulator Turn-On Delay Control. See the REG1, REG2, REG3 Turn-on Delay section for more information. REG3 0x42 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault- interrupts, clear bit to 0 to disable fault-interrupts. REG3 0x42 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG4 0x50 [7:6] - R Reserved. REG4 0x50 [5:0] VSET R/W Output Voltage Selection. See the Output Voltage Programming section for more information. REG4 0x51 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG4 0x51 [6] DIS R/W Output Discharge Control. When activated, LDO output is discharged to GA through 1.5kΩ resistor when in shutdown. Set bit to 1 to enable output voltage discharge in shutdown, clear bit to 0 to disable this function. REG4 0x51 [5] LOWIQ R/W LDO Low-IQ Mode Control. Set bit to 1 for low-power operating mode, clear bit to 0 for normal mode. REG4 0x51 [4:2] DELAY R/W Regulator Turn-On Delay Control. See the REG4, REG5, REG6, REG7 Turn-on Delay section for more information. REG3 0x40 [7:6] - R Reserved. REG4 0x51 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault- interrupts, clear bit to 0 to disable fault-interrupts. |
