/**
* @brief SPI configuration
*
* The atmega2560 has only one hardware SPI with fixed pin configuration, so all
* we can do here, is to enable or disable it...
*
* The fixed pins used, are:
* MOSI - PB2 (Arduino pin 51)
* MISO - PB3 (Arduino pin 50)
* SCK - PB1 (Arduino pin 52)
* SS - PB0 (Arduino pin 53) -> this pin is configured as output, but not used
