Bit Bit Name Initial Value R/W Description

MPB
0
R
Multiprocessor Bit
Stores the value of the multiprocessor bit in receive
data when a multiprocessor format is selected for
receiving in the asynchronous mode. The MPB is a
read-only bit and cannot be written.
0: Multiprocessor bit value in receive data is 0
If RE is cleared to 0 when a multiprocessor format
is selected, the MPB retains its previous value.
1: Multiprocessor bit value in receive data is 1
Note: Clearing the RE bit to 0 in the maltiprocessor
format, which retain its previous value.
0
MPBT
0
R/W Multiprocessor Bit Transfer
Stores the value of the multiprocessor bit added to
transmit data when a multiprocessor format is
selected for transmitting in the asynchronous mode.
The MPBT setting is ignored in the clock synchronous
mode, when a multiprocessor format is not selected,
or when the SCI is not transmitting.
0: Multiprocessor bit value in transmit data is 0
1: Multiprocessor bit value in transmit data is 1
Note: * The only value that can be written is a 0 to clear the flag.
