Section 13 Serial Communication Interface (SCI)
Bit 1—Multiprocessor Bit (MPB): When reception is performed using multiprocessor format in
asynchronous mode, MPB stores the multiprocessor bit in the receive data.
MPB is a read-only bit, and cannot be modified.
Note: * Retains its previous state when the RE bit in SCR is cleared to 0 with multiprocessor
Bit 0—Multiprocessor Bit Transfer (MPBT): When transmission is performed using
multiprocessor format in asynchronous mode, MPBT stores the multiprocessor bit to be added to
the transmit data.
The MPBT bit setting is invalid when multiprocessor format is not used, when not transmitting,
and in clocked synchronous mode.

Description
[Clearing condition]
When data with a 0 multiprocessor bit is received
[Setting condition]
When data with a 1 multiprocessor bit is received
Description
Data with a 0 multiprocessor bit is transmitted
Data with a 1 multiprocessor bit is transmitted
When 0 is written to TDRE after reading TDRE = 1
When the DTC is activated by a TXI interrupt and writes data to TDR
When the TE bit in SCR is 0
When TDRE = 1 at transmission of the last bit of a 1-byte serial transmit character
