3.3 TEMP (AMP overheat) error detection
For detection of a TEMP error, the unit monitors both the TR_DET and PROTECT2 signals. If a TEMP error is detected,
the processes shown below will be performed. The processes shown below are rough operational specifications and are
not the actual commands from the mounted components.
After a TEMP error is detected, the count of protection activation detections will be updated.
