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.

These two bits set the UART0 mode:
Enables the inter-processor communication feature.
If set, enables serial reception. Cleared by software to disable reception.
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.).
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.
Transmit interrupt flag, set by hardware after completion of a serial transfer.
Must be cleared by software.
Receive interrupt flag, set by hardware after completion of a serial
reception. Must be cleared by software.
