^aDetermined by input states: xLO, xHI, and ENABLE. See Input Logic table.

^bShort-to-battery can only be detected when the corresponding GLx = 1. This fault is not detected when ENABLE = 0.

^cShort-to-ground can only be detected when the corresponding GHx = 1. This fault is not detected when ENABLE = 0.

^dBridge fault appears as a short-to-ground fault on all motor phases. This fault is not detected when ENABLE = 0.

^eOff only because V_BOOST≈ V_BAT, which is above the voltage threshold of the Boost regulator voltage control loop.

^fThese faults are not only reported, but also action is taken by the internal logic to protect the A3935 and the system.
