Prepare the Demo
===============
Note: MCUXpresso IDE project default debug console is semihost
1.  Connect a Micro USB cable between the PC host and the LPC-Link USB port (P6) on the 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!
