SM0 and SM1 operating modes (SCON)
SCON bits SM0 and SM1 can operate in the following modes (see Table 14):

SM0
see Table 14.
6
SM1
see Table 14.
5
SM2
Enables the multiprocessor communication feature in Modes 2 and 3. In these
modes, if SM2 is set to 1 then RI will not be activated if the received 9th data bit (RB8) is
0. In Mode 1, if SM2 = 1, then RI will not be activated if a valid stop bit is not received. In
Mode 0, SM2 should be 0.
4
REN
Enables serial reception. Set and cleared by software as required.
3
TB8
9th data bit that will be transmitted in Modes 2 and 3. Set and cleared by software
as required.
2
RB8
In Modes 2 and 3, RB8 is the 9th data bit that is received. In Mode 1, if SM2 = 0,
RB8 is the stop bit that is received. In Mode 0, RB8 is not used.
1TI
Transmit interrupt ag. It is set by hardware at the end of the 8th bit time in Mode 0, or
at the beginning of the stop bit in the other modes. TI must be cleared by software.
0RI
Receive interrupt ag. It is set by hardware at the end of the 8th bit time in Mode 0, or
halfway through the stop bit time in the other modes (except: see SM2). RI must be
cleared by software.
