Short circuit detected: set high when at least one high-side or low-side
switch is switched off by a short-circuit condition. Bits 1 to 6 can be used
to detect the shorted switch.
Open load detected: set high, when at least one active high-side or
low-side switch sinks/sources a current below the open load threshold
current.
Power-supply fail: undervoltage at pin VS detected
