The 4 modes in UART0, Mode 0 ~ 3, are explained later.
SM20: Enables multiprocessor communication feature
REN0: If set, enables serial reception. Cleared by software to disable reception.
TB80: The 9^th transmitted data bit in modes 2 and 3. Set or cleared by the CPU
depending on the function it performs such as parity check, multiprocessor
communication etc.
RB80: In modes 2 and 3, it is the 9^th 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.
TI0: Transmit interrupt flag, set by hardware after completion of a serial transfer.
Must be cleared by software.
RI0: Receive interrupt flag, set by hardware after completion of a serial reception.
Must be cleared by software.
