interface of the MCU from a host system. In boot mode, the program on the on-chip boot ROM
downloads a flash writing application, that will handle the serial transfer and writing of internal flash, to
internal RAM area of the MCU through the UART interface of the MCU.
Internal flash can be programmed by executing a user flash programming application from external
memory.
Boot mode of this LSI is used for downloading data to be written to the FLASH through the UART
