This SFR is used to both send data from the UART and to read received data from the
UART0 receive FIFO.
Write: 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.
Read: Reading SBUF0 retrieves data from the receive FIFO. When read, the oldest byte in
the receive FIFO is returned, and removed from the FIFO. Up to three bytes may be held in
the FIFO. If there are additional bytes available in the FIFO, the RI0 bit will remain at logic
‘1’, even after being cleared by software.
