Description
Transmit End
Indicates that no valid data was in SCTDR during
transmission of the last bit of the transmit character
and transmission has ended.
The TEND flag is read-only and cannot be modified.
0: Indicates that transmission is in progress
[Clearing condition]
•
1: Indicates that transmission has ended
[Setting conditions]

Note: The TEND flag value becomes undefined if
Multiprocessor Bit
Stores the multiprocessor bit found in the receive
data. When the RE bit in SCSCR is cleared to 0, its
previous state is retained.
Multiprocessor Bit Transfer
Specifies the multiprocessor bit value to be added to
the transmit frame.
When 0 is written to TDRE after reading TDRE = 1
By a power-on reset or in standby mode
When the TE bit in SCSCR is 0
When TDRE = 1 during transmission of the last bit
of a 1-byte serial transmit character
data is written to SCTDR by activating the DTC
by a TXI interrupt. In this case, do not use the
TEND flag as the transmit end flag.
