DESCRIPTION
Secondary Output Voltage Selection. Valid when VSEL is
R/W driven high. 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.
Regulator Phase Control. Set bit to 1 for regulator to operate
R/W 180° out of phase with the oscillator, clear bit to 0 for regulator
to operate in phase with the oscillator.
Regulator Mode Select. Set bit to 1 for fixed-frequency PWM
R/W under all load conditions, clear bit to 0 to transit to power-
savings mode under light-load conditions.
R/W
Regulator Turn-On Delay Control. See the REG1, REG2,
REG3 Turn-on Delay section for more information.
R/W
Regulator Fault Mask Control. Set bit to 1 enable to fault-
interrupts, clear bit to 0 to disable fault-interrupts.
R/W
Regulator Power-OK Status. Value is 1 when output voltage
exceeds the power-OK threshold, value is 0 otherwise.
R Reserved.
Primary Output Voltage Selection. Valid when VSEL is driven
R/W low. See the Output Voltage Programming section for more
information.
R Reserved.
Secondary Output Voltage Selection. Valid when VSEL is
R/W driven high. 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/W
Configures regulator behavior with respect to the nPBIN input.
Set bit to 0 to enable regulator when nPBIN is asserted.
Regulator Mode Select. Set bit to 1 for fixed-frequency PWM
R/W under all load conditions, clear bit to 0 to transition to power-
savings mode under light-load conditions.
R/W
Regulator Turn-On Delay Control. See the REG1, REG2,
REG3 Turn-on Delay section for more information.
R/W
Regulator Fault Mask Control. Set bit to 1 enable to fault-
interrupts, clear bit to 0 to disable fault-interrupts.
R/W
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.
Output Discharge Control. When activated, discharges LDO
R/W
output to GA through 1.5kΩ when in shutdown. Set bit to 1 to
enable output voltage discharge in shutdown, clear bit to 0 to
disable this function.
R/W
LDO Low-IQ Mode Control. Set bit to 1 for low-power
operating mode, clear bit to 0 for normal mode.
R/W
Regulator Turn-On Delay Control. See the REG4, REG5,
REG6, REG7 Turn-on Delay section for more information.
R/W
Regulator Fault Mask Control. Set bit to 1 enable to fault-
interrupts, clear bit to 0 to disable fault-interrupts.
