Bit 2—Multiprocessor Mode (MP): This bit selects the multiprocessor format in asynchronous
communication. When multiprocessor format is selected, the parity settings of the parity enable bit
(PE) and parity mode bit (O/E) are ignored. The MP bit is ignored in synchronous communication.
The MP bit is valid only when the MPE bit in the serial/timer control register (STCR) is set to 1.
When the MPE bit is cleared to 0, the multiprocessor communication function is disabled
regardless of the setting of the MP bit.

SCR is an 8-bit readable/writable register that enables or disables various SCI functions.
It is initialized to H'00 by a reset and in the standby modes.
Bit 7—Transmit Interrupt Enable (TIE): This bit enables or disables the TDR-empty interrupt
(TXI) requested when the transmit data register empty (TDRE) bit in the serial status register
(SSR) is set to 1.
