FILE: spi_ex2_loopback_fifo_interrupts.c
This program uses the internal loopback test mode of the SPI module. Both the SPI FIFOs and their interrupts are used.
A stream of data is sent and then compared to the received stream. The sent data looks like this:
0000 0001
0001 0002
0002 0003
....
FFFE FFFF
FFFF 0000
etc..
This pattern is repeated forever.
