FILE: sci_ex2_loopback_interrupts.c
This test uses the internal loop back test mode of the peripheral. Other then boot mode pin configuration, no other hardware configuration is required. Both interrupts and the SCI FIFOs are used.
A stream of data is sent and then compared to the received stream. The SCI-A sent data looks like this:
00 01
01 02
02 03
....
FE FF
FF 00
etc..
The pattern is repeated forever.
