DESCRIPTION

R/W

Output Voltage Selection. See the Output Voltage Programming

section for more information.

R/W

Regulator Enable Bit. Set bit to 1 to enable the regulator, clear

bit to 0 to disable the regulator.

R Reserved.

Output Discharge Control. When activated, LDO output is

R/W

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.

R/W

Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts,

clear bit to 0 to disable fault-interrupts.

R

Regulator Power-OK Status. Value is 1 when output voltage

exceeds the power-OK threshold, value is 0 otherwise.

R Reserved.

R/W

Output Voltage Selection. See the Output Voltage Programming

section for more information.

R/W

Regulator Enable Bit. Set bit to 1 to enable the regulator, clear

bit to 0 to disable the regulator.

R Reserved.

Output Discharge Control. When activated, LDO output is

R/W

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.

R/W

Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts,

clear bit to 0 to disable fault-interrupts.

R

Regulator Power-OK Status. Value is 1 when output voltage

exceeds the power-OK threshold, value is 0 otherwise.

R Reserved.

R/W

Output Voltage Selection. See the Output Voltage Programming

section for more information.

R/W

Regulator Enable Bit. Set bit to 1 to enable the regulator, clear

bit to 0 to disable the regulator.

R Reserved.

Output Discharge Control. When activated, LDO output is

R/W

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.

R/W

Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts,

clear bit to 0 to disable fault-interrupts.

R

Regulator Power-OK Status. Value is 1 when output voltage

exceeds the power-OK threshold, value is 0 otherwise.

R/W

Regulator Enable Bit. Set bit to 1 to enable the regulator, clear

bit to 0 to disable the regulator.

R Reserved.

R/W

nPBIN Assertion Interrupt Control. Set this bit to 1 to generate

an interrupt when nPBIN is asserted.

R/W

nPBIN De-assertion Interrupt Control. Set this bit to 1 to

generate an interrupt when nPBIN is de-asserted.

R Reserved.

Watchdog Soft-Reset Enable. Set this bit to 1 to enable

R/W

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.
