CHEM
The CHEM bit configures the bq2060 for nickel packs
(NiCd or NiMH) or Li-Ion packs. When set the bq2060
employs the configuration parameters in EEPROM des-
ignated for Li-Ion. When not set, the bq2060 employs
theconfiguration parameters designated for nickel.

For Li-Ion packs with individual measurements, LCC0
and LCC1 define the number of series elements and
their voltage measurement inputs. In each case (2, 3, or
4), the bq2060 uses the highest numbered cell voltage
input to measure the pack voltage measurement as re-
turned with Voltage(). For nickel chemistries or Li-Ion
without single-cell measurements, L CC0 and L CC1
must be set to 00. VCELL
4
is the pack voltage input for
this programming.
