This example demonstrates SCI SPI data-transmission between two boards.

Master board first transmits data and then compares all data received from Slave board.

!!!Note!!!

-> How to distinguish Master and Slave board ?

1. Wire Connection

   Master Board      <--->       Slave Board
    SPI CS     -------    NC (Not Connected)
    SPI SO     -------    SPI SI
    SPI SI     -------    SPI SO
	SPI SCK    -------    SPI SCK
      GND      -------      GND

2. Code Description

   a. macro __MAXIMUM_RD_LENGTH__ indicates SPI data quantity.
