Bit 1—Multiprocessor Bit Eeceive (MPBR)
Bit 1 stores the multiprocessor bit in a receive character during multiprocessor format reception in
asynchronous mode.
Bit 1 is a read-only bit and cannot be modified.

Note: * When bit RE is cleared to 0 in SCR3 with the multiprocessor format, bit MPBR is not
Bit 0—Multiprocessor Bit Transfer (MPBT)
Bit 0 stores the multiprocessor bit added to transmit data when transmitting in asynchronous
mode. The bit MPBT setting is invalid when synchronous mode is selected, when the
multiprocessor communication function is disabled, and when not transmitting.
