Function
Temperature prewarning: high = warning
Normal operation: high = output is on, low = output is off
Open-load detection: high = open load, low = no open load
(correct load condition is detected if the corresponding output is
switched off); not affected by SRR
Normal operation: high = output is on, low = output is off
Open-load detection: high = open load, low = no open load

Over-load detected: set high, when at least one output is switched off
by a short-circuit condition or an overtemperature event. Bits 1 to 6 can
be used to detect the affected switch
Inhibit: this bit is controlled by software (bit SI in input register)
High = standby, low = normal operation
Power-supply fail: undervoltage at pin VS detected
