VBAT, then the device will enter Battery Backup Mode and
the I2C interface will be disabled, minimizing VBAT current
drain.
Mode D - This mode combines Legacy Mode battery
switchover with no I2C operation in Battery Backup Mode.
When the VDD voltage drops below VBAT, the device will
enter Battery Backup Mode and the I2C interface will be
disabled, minimizing VBAT current drain.
Note that the IRQ/FOUT open drain output pin is active in
battery backup for all modes, allowing clocking of devices
while in Battery Backup Mode. The pull-up on the pin will
need to go to VBAT, and thus battery mode current draw will
increase accordingly.
