SBUF0.[7:0]: UART0 Buffer Bits 7-0 (MSB-LSB)
This is actually two registers; a transmit and a receive buffer register. When data is moved to
SBUF0, it goes to the transmit buffer and is held for serial transmission. Moving a byte to
SBUF0 is what initiates the transmission. When data is moved from SBUF0, it comes from
the receive buffer.
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.
