6.3.1.2 Monitoring

Several possible faults are monitored by the DLPA3082. If a fault occurred and the type of the fault is read in the Main Status register (0x0C). Subsequently, an interrupt could be generated if a fault occurs. The fault conditions that generate an interrupt could be configured in the Interrupt Mask register (0x0D).
