The signal from the IC is a voltage signal and the signal to the IC is a current signal. In this
way a driving conflict is prevented. Also, it leaves the possibility for the outside world to
see the signal from the IC even while a fault condition is being signalled to the IC in the
meantime, as illustrated in
If a fault is signalled to the IC via the COMM pin this fault is treated identical to hard
switching detected, see
