REGISTER AND BIT DESCRIPTIONS CONT’D BLOCK ADDRESS BIT NAME ACCESS DESCRIPTION REG3 0x31 [7:6] - R Reserved. REG3 0x31 [5:0] VSET1 R/W Secondary Output Voltage Selection. Valid when VSEL is driven high. See the Output Voltage Programming section for more information. REG3 0x32 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG3 0x32 [6:3] - R Reserved. REG3 0x32 [2] 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. REG3 0x32 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts, clear bit to 0 to disable fault-interrupts. REG3 0x32 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG4 0x40 [7:6] - R Reserved. REG4 0x40 [5:0] VSET0 R/W Primary Output Voltage Selection. Valid when VSEL is driven low. See the Output Voltage Programming section for more information REG4 0x41 [7:6] - R Reserved. REG4 0x41 [5:0] VSET1 R/W Secondary Output Voltage Selection. Valid when VSEL is driven high. See the Output Voltage Programming section for more information. REG4 0x42 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG4 0x42 [6:3] - R Reserved. REG4 0x42 [2] 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. REG4 0x42 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts, clear bit to 0 to disable fault-interrupts. REG4 0x42 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG5 0x50 [7:6] - R Reserved. REG5 0x50 [5:0] VSET R/W Output Voltage Selection. See the Output Voltage Programming section for more information. REG5 0x51 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG5 0x51 [6:3] - R Reserved. REG5 0x51 [2] 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. REG5 0x51 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts, clear bit to 0 to disable fault-interrupts. REG5 0x51 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG6 0x58 [7:6] - R Reserved. REG6 0x58 [5:0] VSET R/W Output Voltage Selection. See the Output Voltage Programming section for more information. REG6 0x59 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. |
