Baud Rate
This SFR accesses two registers; a transmit shift register and a receive latch register. When
data is written to SBUF1, it goes to the transmit shift register and is held for serial transmis-
sion. Writing a byte to SBUF1 is what initiates the transmission. A read of SBUF1 returns the
contents of the receive latch.
