Enable the multiprocessor com-
munication feature in mode 2 and 3. In
mode 2 or 3, 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 valid stop
bit was not received. In mode 0, SM2
should be 0.
Set/Cleared by software to Enable/
Disable reception.
The 9th bit that will be transmitted in
mode 2 and 3. Set/Cleared by software.
In modes 2 and 3, RB8 is the 9th data
bit that was received. In mode 1, if
SM2=0, RB8 is the stop bit that was
received. In mode 0, RB8 is not used.
Transmit interrupt flag. Set by hardware
at the end of the eighth bit time in mode
0, or at the beginning of the stop bit in
the other modes. Must be cleared by
software.
Receive interrupt flag. Set by hardware
at the end of the eighth bit time in mode
0, or halfway through the stop bit time
in the other modes (except see SM2).
Must be cleared by software.
