The CONFIG_COV register determines cell overvoltage threshold voltage.
[7] (DISABLE):
[5..0] (COV[5] … [0]):
Disables the overvoltage function when set
0 = Overvoltage function enabled
1 = Overvoltage function disabled
Configuration bits with corresponding voltage threshold
0x00 = 2 V; each binary increment adds 50 mV until 0x3c = 5 V.

The CONFIG_COVT register determines cell overvoltage detection delay time.
[7] ( μ s/ms):
[4..0] COVD:
Determines the units of the delay time, microseconds or milliseconds
0 = Microseconds
1 = Milliseconds
0x01 = 100; each binary increment adds 100 until 0x1f = 3100
Note:
When this register is programmed to 0x00, the delay becomes 0s AND the COV state
is NOT latched in the COV_FAULT[] register. In this operating mode, the overvoltage
state for a cell is virtually instantaneous in the COV_FAULT[] register. This mode may
cause system firmware to miss a dangerous cell overvoltage condition.

[7] (DISABLE):
[5..0] (CUV[4] … [0]):
Disables the undervoltage function when set
0 = Undervoltage function enabled
1 = Undervoltage function disabled
Configuration bits with corresponding voltage threshold
0x00 = 0.7 V; each binary increment adds 100 mV until 0x1a = 3.3 V.
