Write_FIFO
Write_FIFO
writes a value into the send-FIFO of a specified RSxxx interface.

Parameters
Notes
The instruction checks first if there is at least one free memory cell in the
send-FIFO. If so, the transferred value is written into the FIFO (return
value 0); otherwise a 1 is returned, indicating that the FIFO is full and
