Description: This bitfield configures which protections will disable the DSG FET. NOTE - For the DSG FET turnoff action to occur immediately when a fault is detected, this value should only be set to 0x80 or 0xE4. Setting it to other values can cause FET turnoff action to be delayed by up to 250ms in NORMAL mode or 1 second in SLEEP mode
