NAME ACCESS
DESCRIPTION
SYS
0x00
Battery Voltage Level Interrupt Mask. Set this bit to 1 to unmask
[7] nBATLEVMSK R/W 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
Battery Voltage Detect Threshold. Defines the BATLEV voltage
R/W 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.

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
Regulator Phase Control. Set bit to 1 for the regulator to operate
R/W 180° out of phase with the oscillator, clear bit to 0 for the
regulator to operate in phase with the oscillator.
