This sets the initial full charge battery capacity
stored in FCC. FCC is updated with the actual full
to empty discharge capacity after a valid discharge
from RM = FCC to Voltage() = EDV1.

FLAGS1 should be set to 10h before pack shipment to
inhibit undesirable writes to the bq2092. (WRINH = 1.)
See FLAGS2 register for the bit description and the
proper value for programming FLAGS2. Selects rela-
tive display mode, selects NiMH compensation factors,
and enables bq2092 Smart Charger control.
The current gain measurement and current integration
gain are related and defined for the bq2092 current
measurement. 0x0c = 37.5/sense resistor value in
ohms.
The value programmed is the two's complement of the
threshold voltage in mV.
