Description
Transmit End
This bit is set to 1 when no error signal has been sent
back from the receive side and the next transmit data is
ready to be transferred to TDR.
[Setting conditions]
•
•
•
The timing of bit setting differs according to the register
setting as follows:
When GM = 0 and BLK = 0, 2.5 etu after transmission
starts
When GM = 0 and BLK = 1, 1.0 etu after transmission
starts
When GM = 1 and BLK = 0, 1.5 etu after transmission
starts
When GM = 1 and BLK = 1, 1.0 etu after transmission
starts

Multiprocessor
This bit is not used in smart card interface mode.
Multiprocessor Bit Transfer
Write 0 to this bit in smart card interface mode.
Power-on reset or software standby mode
When the TE bit in SCR is 0 and the ESR bit is also 0
When the ESR bit is 0 and the TDRE bit is 1 after the
specified interval following transmission of 1-byte data
When 0 is written to TDRE after reading TDRE = 1
When the DMAC is activated by a TXI interrupt
When the DTC is activated by a TXI interrupt and
transmit data is transferred to TDR while the DISEL
bit in DTMR of the DTC is 0
