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
    CSI CS     -------    NC (Not Connected)
    CSI SO     -------    CSI SI
    CSI SI     -------    CSI SO
	CSI SCK    -------    CSI SCK
      GND      -------      GND

2. Code Description

   a. macro __MAXIMUM_RD_LENGTH__ indicates SPI data quantity.
