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 2
TEND Description
0 [Clearing conditions]
• When 0 is written in TDRE after reading TDRE = 1
• When the DTC is activated by a TXI interrupt and writes data to TDR
1 [Setting conditions] (Initial value
)
• When the TE bit in SCR is 0
• When TDRE = 1 at transmission of the last bit of a 1-byte serial transmit character
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.
Bit 1
MPB Description
0 [Clearing condition] (Initial value)
*
When data with a 0 multiprocessor bit is received
1 [Setting condition]
When data with a 1 multiprocessor bit is received
Note: * Retains its previous state when the RE bit in SCR is cleared to 0 with multiprocessor
format.
