Bit 1—Multiprocessor Bit (MPB): MPB stores the value of the multiprocessor bit in receive data
when a multiprocessor format is selected for receiving in asynchronous mode. The MPB is a read-
only bit and cannot be written.

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

13.2.8
The bit rate register (BRR) is an eight-bit register that, together with the baud rate generator clock
source selected by the CKS1 and CKS0 bits in the serial mode register (SMR), determines the
serial transmit/receive bit rate.
The CPU can always read and write to BRR. BRR is initialized to H'FF by a reset and in standby
mode. SCI0 and SCI1 have independent baud rate generator control, so different values can be set
in the two channels.
Table 13.3 shows examples of BRR settings in asynchronous mode; table 13.4 shows examples of
BBR settings in synchronous mode.

Description
Multiprocessor bit value in receive data is 0
If RE is cleared to 0 when a multiprocessor format is selected, MPB retains its
previous value.
Multiprocessor bit value in receive data is 1
Description
Multiprocessor bit value in transmit data is 0
Multiprocessor bit value in transmit data is 1
