Mode 3
The only difference between Mode 2 and Mode 3 is that in Mode 3 either internal baud rate generator
or timer 1 can be use to specify baud rate.
The S0BUF register is used to read/write data to/from the serial 0 interface.
Serial Interface 0 Control Register (S0CON): 0x9B
0x00
Transmit and receive data are transferred via this register.

S0CON.6

S0CON.5
SM20
Enables the inter-processor communication feature.
S0CON.4
REN0
If set, enables serial reception. Cleared by software to disable reception.
S0CON.3
TB80
The 9th transmitted data bit in Modes 2 and 3. Set or cleared by the MPU,
depending on the function it performs (parity check, multiprocessor
communication etc.).
S0CON.2
RB80
In Modes 2 and 3 it is the 9th data bit received. In Mode 1, if SM20 is 0,
RB80 is the stop bit. In Mode 0 this bit is not used. Must be cleared by
software.
S0CON.1
TI0
Transmit interrupt flag, set by hardware after completion of a serial transfer.
Must be cleared by software.
S0CON.0
RI0
Receive interrupt flag, set by hardware after completion of a serial
reception. Must be cleared by software.
