REGISTER AND BIT DESCRIPTIONS BLOCK ADDRESS BIT NAME ACCESS DESCRIPTION SYS 0x00 [7] nBATLEVMSK R/W Battery Voltage Level Interrupt Mask. Set this bit to 1 to unmask the interrupt. See the Programmable Battery Voltage Monitor section for more information SYS 0x00 [6] nBATSTAT R Battery Voltage Status. Value is 1 when BATLEV interrupt is generated, value is 0 otherwise. SYS 0x00 [5] VBATDAT R Battery Voltage Monitor real time status. Value is 1 when VBAT < BATLEV, value is 0 otherwise. SYS 0x00 [4] - R/W Reserved. SYS 0x00 [3:0] BATLEV R/W Battery Voltage Detect Threshold. Defines the BATLEV voltage threshold. See the Programmable Battary Voltage Monitor section for more information. SYS 0x01 [7] nTMSK R/W Thermal Interrupt Mask. Set this bit to 1 to unmask the interrupt. SYS 0x01 [6] TSTAT R Thermal Interrupt Status. Value is 1 when a thermal interrupt is generated, value is 0 otherwise. SYS 0x01 [5:0] - R/W Reserved. REG1 0x10 [7:6] - R Reserved. REG1 0x10 [5:0] VSET0 R/W Primary Output Voltage Selection. See the Output Voltage Programming section for more information REG1 0x12 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG1 0x12 [6:3] - R Reserved. REG1 0x12 [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. REG1 0x12 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts, clear bit to 0 to disable fault-interrupts. REG1 0x12 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG2 0x20 [7:6] - R Reserved. REG2 0x20 [5:0] VSET0 R/W Primary Output Voltage Selection. Valid when VSEL is driven low. See the Output Voltage Programming section for more information REG2 0x21 [7:6] - R Reserved. REG2 0x21 [5:0] VSET1 R/W Secondary Output Voltage Selection. Valid when VSEL is driven high. See the Output Voltage Programming section for more information. REG2 0x22 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG2 0x22 [6:3] - R Reserved. REG2 0x22 [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. REG2 0x22 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts, clear bit to 0 to disable fault-interrupts. REG2 0x22 [0] OK R Regulator Power-OK Status.
