This section describes the modules integrated in the device MCU domain.
The Microcontroller Unit Domain (MCU Domain) is a “chip-in-a-chip” concept and it operates using separate clock sources and resets. This allows the MCU Domain to function continuously regardless of the state of the rest of the device, including periods in which the rest of the device is held in reset or powered down. The MCU island integrates communication peripherals such as SPI, I2C, and UART which are expected to be used for safety critical communication, so if the main SoC goes down, the MCU island can communicate this information to the rest of the system.
