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.

Bit 2: TEND

Description

Transmission is in progress.

TEND is cleared to 0 when software reads TDRE after it has been set to 1, then

writes 0 in TDRE, or data is written in SCTDR.

End of transmission.

(Initial value)

TEND is set to 1 when the chip is reset or enters standby mode, TE is cleared to

0 in the serial control register (SCSCR), or 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.

Bit 1: MPB

Description

Multiprocessor bit value in receive data is 0.

(Initial value)

If RE is cleared to 0 when a multiprocessor format is selected, the MPB retains

its previous value.

Multiprocessor bit value in receive data is 1.

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

Multiprocessor bit value in transmit data is 0.

(Initial value)

Multiprocessor bit value in transmit data is 1.
