Section 15 Serial Communication Interface (SCI, IrDA)
Bit 2—Transmit End (TEND): Indicates that there is no valid data in TDR when the last bit of
the transmit character is sent, and transmission has been ended.
The TEND flag is read-only and cannot be modified.

Bit 1—Multiprocessor Bit (MPB): When reception is performed using a multiprocessor format
in asynchronous mode, MPB stores the multiprocessor bit in the receive data.
MPB is a read-only bit, and cannot be modified.

Description
[Clearing condition]
When data with a 0 multiprocessor bit is received
[Setting condition]
When data with a 1 multiprocessor bit is received
When 0 is written in TDRE after reading TDRE = 1
When the DTC is activated by a TXI interrupt and writes data to TDR
When the TE bit in SCR is 0
When TDRE = 1 at transmission of the last bit of a 1-byte serial transmit character
