Description
Transmit End
This bit is set to 1 when no error signal has been
sent back from the receiving end and the next
transmit data is ready to be transferred to TDR.
[Setting conditions]
•
•
Timing to set this bit differs according to the
register settings.
GM = 0, BLK = 0: 2.5 etu *
GM = 0, BLK = 1: 1.5 etu *
GM = 1, BLK = 0: 1.0 etu *
GM = 1, BLK = 1: 1.0 etu *

Multiprocessor Bit
This bit is not used in Smart Card interface mode.
Multiprocessor Bit Transfer
Write 0 to this bit in Smart Card interface mode.
[Clearing conditions]
When the TE bit in SCR is 0 and the ERS bit is
also 0
If the ERS bit is 0 and the TDRE bit is 1 after
the specified interval after transmission of 1-
byte data
When 0 is written to TEND after reading TEND
= 1
When the DMAC or DTC is activated by a TXI
interrupt and writes data to TDR
