BATTERY DROP CAUSE
[Function]
This notifies a drop in the battery voltage.
[Operation]
A drop in voltage of the data storage battery located on the front door of the controller is checked
when the power is turned ON. If the voltage is below the specified voltage (approx. 2.6V), the
"Battery alarm (BATAL)" signal turns ON, and bit 0 of this data is set to "1".
(Note) This data will not change until the battery voltage is recovered to a normal value.
