Interrupt Generation - and Status Bit Logic
The interrupt flags of the high side module are having the following behaviour:
Overcurrent detection:
the overcurrent detection interrupt flag is a level sensitive interrupt flag. This flag is
set when the overcurrent condition occurs and stays persistent until the condition is removed.
Overtemperature detection:
the overtemperature detection interrupt flag is a level sensitive interrupt flag.
This flag is set when the overtemperature condition occurs, but can be cleared immediately. The
overtemperature status of the overtemperature condition can then still be monitored in the dedicated status
register, which is placed in the same interrupt status register.
Open load detection:
the open load detection interrupt flag is a level sensitive interrupt flag. This flag is set
when the open condition occurs, but can be cleared immediately. The open load status of the open load
condition can then still be monitored in the dedicated status register, which is placed in the same interrupt
status register.
