	The purpose of the M1553_RT_Receive_FIFO is to illustrate the methods to call in the naibrd library to configure the 1553 channel as a Remote Terminal, legalize Subaddress 2 for Tx, Rx and Broadcast messages, and set it up to receive data using double buffers and transmit data from two alternating Tx buffers (active and inactive). If a Rx message is received, the received data and message information will be displayed via message FIFO. If a Tx message is received, the data in the active Tx buffer will be sent to the bus. While the RT is running, Tx buffer data will be updated periodically by incrementing all 32 data words of Tx data. If a Tx message is received, the message information will be displayed via message FIFO. This application demonstrates the usage of the following naibrd 1553 routines.
