3 9-bit UART variable
SM2 Enables the multiprocessor communication feature 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
9^th 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.
REN Enables serial reception. Set by software to enable reception. Clear by
software to disable reception.
TB8 TB8 is the 9^th data bit that will be transmitted in Modes 2 and 3. Set or
clear by software as desired.
RB8 In Modes 2 and 3, it is the 9^th 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.
TI TI is the transmit interrupt flag. Set by hardware at the end of the 8^th bit
time in Mode 0, or at the beginning of the stop bit in the other modes, in
any serial transmission. It must be cleared by software.
RI RI is the receive interrupt flag.
