Multiprocessor Bit
MPB stores the multiprocessor bit in the receive frame.
When the RE bit in SCR is cleared to 0 its previous state
is retained.
Multiprocessor Bit Transfer
MPBT stores the multiprocessor bit to be added to the
transmit frame.
When the stop bit is 0
When 0 is written to FER after reading FER = 1
When a parity error is detected during reception
When 0 is written to PER after reading PER = 1
When the TE bit in SCR is 0
When TDRE = 1 at transmission of the last bit of a 1-
byte serial transmit character
When 0 is written to TDRE after reading TDRE = 1
When a TXI interrupt request is issued allowing the
DTC to write data to TDR
