Function
Temperature prewarning: high = warning
(overtemperature shutdown see remark below)
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)
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)

Short circuit detected: set high, when at least one output is switched off by a
short circuit condition
Inhibit: this bit is controlled by software (bit SI in input register) and hardware
inhibit (pin INH). High = standby, low = normal operation
Power supply fail: undervoltage at pin VS detected
Note:
Bit 0 to 15 = high: overtemperature shutdown
