Enables the multiprocessor communication feature in Modes 2 and 3. In
Mode 2 or 3, if SM2 is set, then RI will not be activated, RB8 and S0BUF will not
be loaded if the received 9
will not be activated, RB8 and S0BUF will not be loaded if no valid stop bit was
received. In Mode 0, SM2 has no influence.
Enables serial reception. Set by software to enable reception. Cleared by
software to disable reception.
Is the 9
software as desired.
In Modes 2 and 3, RB8 is the 9
logic 0, RB8 is the stop bit that was received. In Mode 0, RB8 is not used.
Loading of RB8 in Modes 1, 2 and 3 depends on SM2.
