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
