SLUUBT5C November 2018 – June 2021 BQ40Z80
This command disables/enables control of the CHG, DSG, and PCHG FET by the firmware. The initial setting is loaded from Mfg Status Init[FET_EN]. If the ManufacturingStatus()[FET_EN] = 0, sending this command allows the FW to control the PCHG, CHG, and DSG FETs and the ManufacturingStatus()[FET_EN] = 1 and vice versa.
In UNSEALED mode, the ManufacturingStatus()[FET_EN] status is copied to Mfg Status Init[FET_EN] when the command is received by the gauge. The BQ40Z80 device remains on its latest FET control status prior to a reset.
