SCI Data Register (SCIDR)
This register contains the received or transmitted data character, depending on whether it is
read from or written to.
The Data register performs a double function (read and write) since it is composed of two
registers, one for transmission (TDR) and one for reception (RDR).
The TDR register provides the parallel interface between the internal bus and the output
shift register (see
input shift register and the internal bus (see
SCI Baud Rate Register (SCIBRR)
