UART SERIAL INTERFACE
The serial port is full duplex, meaning it can transmit and receive
simultaneously. It is also receive-buffered, meaning it can com-
mence reception of a second byte before a previously received
byte has been read from the receive register. However, if the first
byte still has not been read by the time reception of the second
byte is complete, the first byte will be lost. The physical interface
to the serial data network is via pins RXD(P3.0) and TXD(P3.1)
while the SFR interface to the UART is comprised of SBUF
and SCON, as described below.
SBUF
The serial port receive and transmit registers are both accessed
through the SBUF SFR (SFR address = 99H). Writing to
SBUF loads the transmit register and reading SBUF accesses a
physically separate receive register.

UART Serial Mode Select Bits.
These bits select the Serial Port operating mode as follows:
SM0
SM1
Selected Operating Mode
0
0
Mode 0: Shift Register, fixed baud rate (Core_Clk/2)
0
1
Mode 1: 8-bit UART, variable baud rate
1
0
Mode 2: 9-bit UART, fixed baud rate (Core_Clk/64) or (Core_Clk/32)
1
1
Mode 3: 9-bit UART, variable baud rate
Multiprocessor Communication Enable Bit.
Enables multiprocessor communication in Modes 2 and 3. In Mode 0, SM2 should be cleared.
In Mode 1, if SM2 is set, RI will not be activated if a valid stop bit was not received. If SM2 is
cleared, RI will be set as soon as the byte of data has been received. In Modes 2 or 3, if SM2 is set,
RI will not be activated if the received ninth data bit in RB8 is 0. If SM2 is cleared, RI will be set
as soon as the byte of data has been received.
Serial Port Receive Enable Bit.
Set by user software to enable serial port reception.
Cleared by user software to disable serial port reception.
Serial Port Transmit (Bit 9).
The data loaded into TB8 will be the ninth data bit that will be transmitted in Modes 2 and 3.
Serial Port Receiver Bit 9.
The ninth data bit received in Modes 2 and 3 is latched into RB8. For Mode 1 the stop bit is
latched into RB8.
Serial Port Transmit Interrupt Flag.
Set by hardware at the end of the eighth bit in Mode 0, or at the beginning of the stop bit in
Modes 1, 2, and 3. TI must be cleared by user software.
Serial Port Receive Interrupt Flag.
Set by hardware at the end of the eighth bit in Mode 0, or halfway through the stop bit in
Modes 1, 2, and 3. RI must be cleared by software.
