Function
7:0 SBUF1[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 SBUF1, it goes to the transmit shift register and is held for
serial transmission. Writing a byte to SBUF1 initiates the transmission. A read of
SBUF1 returns the contents of the receive latch.
