Bit 0: Reserved.
Bit 1: SRC_SINK_B. If set, then BMD sources current; otherwise, BMD sinks current.
Bit 2: Reserved.
Bit 3: Reserved.
Bit 4: QT TX-P LO Mask. If set, then TX-P low does not have the ability to cause a safety fault.
Bit 5: QT HIGH BIAS Mask. If set, then HIGH BIAS does not have the ability to cause a safety fault.
Bit 6: QT TX-P HI Mask. If set, then TX-P high does not have the ability to cause a safety fault.
Bit 7: FETG_POL. If set, then FETG asserts with a high logic level; otherwise, it asserts with a low logic level.
