Section 13 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.
Bit 1
MPB
Description
0
Multiprocessor bit value in receive data is 0*
1
Multiprocessor bit value in receive data is 1
Note: * If the RE bit in SCR is cleared to 0 when a multiprocessor format is selected, MPB retains
its previous value.
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.
Bit 1
MPBT
Description
0

1
Multiprocessor bit value in transmit data is 1
