REGISTER AND BIT DESCRIPTIONS CONT’D BLOCK ADDRESS BIT NAME ACCESS DESCRIPTION REG10 0x80 [5:0] VSET R/W Output Voltage Selection. See the Output Voltage Programming section for more information. REG10 0x81 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG10 0x81 [6:3] - R Reserved. REG10 0x81 [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. REG10 0x81 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts, clear bit to 0 to disable fault-interrupts. REG10 0x81 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG11 0x90 [7:6] - R Reserved. REG11 0x90 [5:0] VSET R/W Output Voltage Selection. See the Output Voltage Programming section for more information. REG11 0x91 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG11 0x91 [6:3] - R Reserved. REG11 0x91 [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. REG11 0x91 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts, clear bit to 0 to disable fault-interrupts. REG11 0x91 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG12 0xA0 [7:6] - R Reserved. REG12 0xA0 [5:0] VSET R/W Output Voltage Selection. See the Output Voltage Programming section for more information. REG12 0xA1 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG12 0xA1 [6:3] - R Reserved. REG12 0xA1 [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. REG12 0xA1 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts, clear bit to 0 to disable fault-interrupts. REG12 0xA1 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG13 0xB1 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG13 0xB1 [6:0] - R Reserved. PB 0xC0 7 nPBAMSK R/W nPBIN Assertion Interrupt Control. Set this bit to 1 to generate an interrupt when nPBIN is asserted. PB 0xC0 6 nPBDMSK R/W nPBIN De-assertion Interrupt Control. Set this bit to 1 to generate an interrupt when nPBIN is de-asserted. PB 0xC0 [5:2] - R Reserved. PB 0xC0 1 WDSREN R/W Watchdog Soft-Reset Enable. Set this bit to 1 to enable watchdog function. When the watchdog timer expires, the PMU commences a soft-reset routine. This bit is automatically reset to 0 when entering sleep mode. |
