Prepare the Demo
===============
1.  Connect a type-c USB cable between the host PC and the MCU-Link USB port (J13) on the target board.
2.  Open a serial terminal with the following settings:
    - 115200 baud rate
    - 8 data bits
    - No parity
    - One stop bit
    - No flow control
3.  Download the program to the target board.
4.  Reset the SoC and run the project.

Running the demo
===============
When the demo runs successfully, the log would be seen on the terminal like:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
SPI board to board interrupt master example started!

SPI transfer finished!
