0000 is the bq33100 power on reset default.
OCDV3, OCDV2, OCDV1, OCDV0 — Sets the overcurrent voltage threshold (VSRP-VSRN)) in discharging of
the integrated AFE.
0x0 - 0xf = sets the short circuit in discharging delay between 0ms - 915ms in 61ms steps.
[RSNS] = 0, 0x0 - 0xf sets the voltage threshold between 50 mV and 200 mV in 10 mV steps.
[RSNS] = 1, 0x0 - 0xf sets the voltage threshold between 20 mV and 100 mV in 5 mV steps.
OCDV (b7...b4) — Not used.

8.5.3.4.2 OC Dsg Time
The OC Dsg Time is programmed into the OCDD register of the integtrated AFE device. The OC Dsg Time sets
the overcurrent in discharging delay. Changes to this data flash value requires a firmware full reset or a power
reset of the bq33100 to take effect.
