SBUF0.[7:0]: UART0 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 is what initiates the transmission. A read of SBUF0 returns the contents of the receive
latch.
SADDR0.[7:0]: UART0 Slave Address
The contents of this register are used to define the UART0 slave address. Register SADEN0 is a bit
mask to determine which bits of SADDR0 are checked against a received address: corresponding bits
set to logic 1 in SADEN0 are checked; corresponding bits set to logic 0 are “don’t cares”.
SADEN0.[7:0]: UART0 Slave Address Enable
Bits in this register enable corresponding bits in register SADDR0 to determine the UART0 slave
address.
0: Corresponding bit in SADDR0 is a “don’t care”.
1: Corresponding bit in SADDR0 is checked against a received address.
