Serial port receiver interrupt flag
RI 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, in any serial reception (exception see
SM2). RI must be cleared by software.
Serial port transmitter interrupt flag
TI 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, in any serial transmission. TI must be
cleared by software.
Serial port receiver bit 9
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.
Serial port transmitter bit 9
TB8 is the 9th data bit that will be transmitted in
modes 2 and 3. Set or cleared by software as
desired.
Enable receiver of serial port
Enables serial reception. Set by software to enable
serial reception. Cleared by software to disable
serial reception.
Enable serial port multiprocessor
communication in modes 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 a
valid stop bit was not received. In mode 0, SM2
should be 0.
