BATS Voltage High Select — This bit selects the trigger level for the Voltage Level High Condition (BVHC).
0 Voltage level V
1 Voltage level V
BATS Voltage Low Select — This bit selects the trigger level for the Voltage Level Low Condition (BVLC).
00 Voltage level V
01 Voltage level V
10 Voltage level V
11 Voltage level V
BATS VSUP ADC Connection Enable — This bit connects the VSUP pin through the resistor chain to ground
and connects the ADC channel to the divided down voltage. This bit can be set only if the BSEAE bit is cleared.
0 ADC Channel is disconnected
1 ADC Channel is connected
BATS VSUP Level Sense Enable — This bit connects the VSUP pin through the resistor chain to ground and
enables the Voltage Level Sense features measuring BVLC and BVHC. This bit can be set only if the BSESE bit
is cleared.
0 Level Sense features disabled
1 Level Sense features enabled
BATS VSENSE ADC Connection Enable — This bit connects the VSENSE pin through the resistor chain to
ground and connects the ADC channel to divided down voltage. Setting this bit will clear bit BSUAE .
0 ADC Channel is disconnected
1 ADC Channel is connected
BATS VSENSE Level Sense Enable — This bit connects the VSENSE pin through the resistor chain to ground
and enables the Voltage Level Sense features measuring BVLC and BVHC.Setting this bit will clear bit BSUSE
