Bit Bit Name Initial Value R/W Description
2 TEND 1 R Transmit End
[Setting conditions]
• When the TE bit in SCR is 0
• When TDRE = 1 at transmission of the last bit
of a 1-byte serial transmit character
[Clearing conditions]
• When 0 is written to TDRE after reading TDRE
= 1
• When the DMAC or DTC is activated by a TXI
interrupt and writes data to TDR
1 MPB 0 R Multiprocessor Bit
MPB stores the multiprocessor bit in the receive
data. When the RE bit in SCR is cleared to 0 its
previous state is retained.
0 MPBT 0 R/W Multiprocessor Bit Transfer
MPBT sets the multiprocessor bit to be added to
the transmit data.
Note: * Only 0 can be written, to clear the flag.
