The MCU domain and main domain of the AM62x are powered using a common power source and common clock. The main domain can be reset independently from the MCU domain. An MCU domain reset results in an entire device reset. There are several on-chip diagnostics to aid in detection of common cause failures from clock, power, and reset. Dual clock comparators, on-chip oscillator clock detection, internal Power OK (POK) monitors, and temperature monitors along with thermal sensors are examples of such diagnostics. The safety concept also relies on external monitoring such as a windowed watchdog for detection of common cause failures on the device.
