Contact Maxim for details on how to configure these
registers. The default value is appropriate for some
Li+ batteries.
To unlock the TABLE registers, write 0x57 to address
0x3F, and 0x4A to address 0x3E. While the TABLE is
unlocked, no ModelGauge registers are updated, so
relock as soon as possible by writing 0x00 to address
0x3F, and 0x00 to address 0x3E.
Writing a value of 0x5400 to this register causes the device
to completely reset as if power had been removed. Use
with caution (see the
The reset occurs when the last bit has been clocked
in. The IC does not respond with an I
command sequence.
