SBUF1.[7:0]: UART1 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 SBUF1, it goes to the transmit shift register and is held for serial transmission. Writing a
byte to SBUF1 is what initiates the transmission. A read of SBUF1 returns the contents of the receive
latch.
SADDR1.[7:0]: UART1 Slave Address
The contents of this register are used to define the UART1 slave address. Register SADEN1 is a bit
mask to determine which bits of SADDR1 are checked against a received address: corresponding bits
set to logic 1 in SADEN1 are checked; corresponding bits set to logic 0 are “don’t cares”.
SADEN1.[7:0]: UART1 Slave Address Enable
Bits in this register enable corresponding bits in register SADDR1 to determine the UART1 slave
address.
0: Corresponding bit in SADDR1 is a “don’t care”.
1: Corresponding bit in SADDR1 is checked against a received address.
