Table 26.3. SBUF0 Register Bit Descriptions
Function
Serial Data Buffer Bits.
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
transmission. Writing a byte to SBUF0 initiates the transmission. A read of SBUF0
returns the contents of the receive latch.
