12. Serial Communication Interface
Bit 1—Multiprocessor bit (MPB): Stores the value of the multiprocessor bit in the receive data
when a multiprocessor format is used in asynchronous mode. MPB is a read-only bit, and cannot
be written.

Note:
Bit 0—Multiprocessor Bit Transfer (MPBT): Stores the value of the multiprocessor bit added to
transmit data when a multiprocessor format in selected for transmitting in asynchronous mode.
The MPBT bit setting is ignored in synchronous mode, when a multiprocessor format is not
selected, or when the SCI cannot transmit.

12.2.8
BRR is an 8-bit register that sets the serial transmit/receive bit rate in accordance with the baud
rate generator operating clock selected by bits CKS0 and CKS1 in SMR.
BRR can be read or written to by the CPU at all times.
BRR is initialized to H'FF by a reset and in standby mode.
As baud rate generator control is performed independently for each channel, different values can
be set for each channel.
