Figure 16.8. SBUF0: Serial (UART0) Port Data Buffer Register

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 transmission. Writing a

byte to SBUF0 initiates the transmission. A read of SBUF0 returns the contents of the receive latch.
