Bit 2—Transmit End (TEND): Indicates that when the last bit of a serial character was
transmitted, SCTDR did not contain valid data, so transmission has ended. TEND is a read-only
bit and cannot be written to.
Bit 2: TEND Description
0 Transmission is in progress
[Clearing condition]
TEND is cleared to 0 when software reads TDRE after it has been set to 1, then
writes 0 to TDRE.
1 End of transmission (Initial value)
[Setting conditions]
(1) TEND is set to 1 when the chip is reset or enters standby mode.
(2) When TE is cleared to 0 in the serial control register (SCSCR).
(3) If TDRE is 1 when the last bit of a one-byte serial character is transmitted.
Bit 1—Multiprocessor Bit (MPB): Stores the value of the multiprocessor bit in receive data
when a multiprocessor format is selected for receiving in asynchronous mode. MPB is a read-only
bit and cannot be written to.
Bit 1: MPB Description
0 Multiprocessor bit value in receive data is 0
*
(Initial value)
1 Multiprocessor bit value in receive data is 1
Note: * If RE is cleared to 0 when a multiprocessor format is selected, MPB retains its
previous value.
Bit 0—Multiprocessor Bit Transfer (MPBT): Stores the value of the multiprocessor bit added to
transmit data when a multiprocessor format is selected for transmitting in asynchronous mode.
The MPBT setting is ignored in synchronous mode, when a multiprocessor format is not selected,
or when the SCI is not transmitting.
Bit 0: MPBT Description
0 Multiprocessor bit value in transmit data is 0 (Initial value)
1 Multiprocessor bit value in transmit data is 1
