Sets 7-bit CH DAC voltage for A/D conversion (POR state is all zeros with DAC and comparators off).
DAC0–DAC6
Sets OUT Output Voltage (POR state is V
OUT
= 3.0V).
OV0–OV4
1 = Allows LBO to turn on the backup regulator and disable the DC-DC converter (POR state is no
connection between LBO and BACKUP).
LBO_Sets_BACKUP
1 = Turns on the backup linear regulator from NICD to OUT and disables the DC-DC converter (POR
state is BACKUP off). Setting this bit overrides 1mA_CHG, 15mA_CHG, and LBO_Sets_BACKUP
(Figure 1).
BACKUP
1 = Turns on the selected charge current to NICD. If both are set, the charge current is 15mA (POR
state is off).
1 = Turns on the selected switch (POR state is off).
1 = Turns on the selected regulator (POR state is off).
1 = Run Mode, 0 = Coast Mode (POR state is Coast Mode).

FUNCTION
CH_OUT and LBO output bits. A 1 indicates

greater than the CH DAC voltage or that LBI is
less than 0.6V.
