8.5.2.2.12 Extended SBS Commands
Also available through ManufacturerAccess in sealed mode are some of the extended SBS commands. The
commands available are listed below. The result of these commands need to be read from ManufacturerAccess
after a write to ManufacturerAccess.
8.5.2.2.12.1 FETControl(0x46)
This write- and read-word function allows direct control of the CHG FET for test purposes. The bq33100
overrides this command unless in normal mode.

CHG — Charge (CHG) FET Control
0 = CHG FET is turned OFF.
1 = CHG FET is turned ON.
8.5.2.2.12.2 SafetyAlert (0x50)
This read-word function returns indications of pending safety issues, such as running safety timers, or fail
counters that are nonzero but have not reached the required time or value to trigger a SafetyStatus failure.
These flags do not cause the FAULT pin to be set.
