This alert is reported by the HwResetHandler_TC3x (RSTH) component when there is various data integrity (ECC) alarms. The MCU has a number of reset sources. This diagnostic symbolizes those of them. Some are not required as diagnostic by the safety concept, yet they exists in the MCU. Some are required, but very microcontroller specific.
