SFR Address:
Bits7 – 0: SBUF0[7:0]: Serial Data Buffer Bits 7 – 0 (MSB – LSB)
This SFR accesses two registers; a transmit shift register and a receive latch register. When
data is written to SBUF0, it goes to the transmit shift register and is held for serial transmis-
sion. Writing a byte to SBUF0 initiates the transmission. A read of SBUF0 returns the con-
tents of the receive latch.
