States mode and enters either the Standard Battery
States mode or the AC Adapter States mode.
Status and Configuration
BATSTAT and
ACPRES
provide information to an exter-
nal controller. Table 4 shows the different states of
BATSTAT and
ACPRES
.
In the AC Adapter States mode, the BATSEL Action
Delay (see
Electrical Characteristics
) allows the exter-
nal controller to tell if both batteries are absent. When
both batteries are absent in the AC Adapter States
mode and BATSEL changes states, BATSTAT is imme-
diately updated. However, changes to the connection
states are delayed (see Table 1 for connection states).
