FILE: spi_ex3_external_loopback.c
This program uses the external loopback between two SPI modules. Both the SPI FIFOs and interrupts are not used in this example. SPIA is configured as a peripheral and SPI B is configured as controller. This example demonstrates full duplex communication where both controller and peripheral transmits and receives data simultaneously.
