H8S/2215 Group
Bit Bit Name Initial Value R/W Description
2 TEND 1 R 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]
When the TE bit in SCR is 0 and the ERS 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.
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
[Clearing conditions]
When 0 is written to TDRE after reading TDRE = 1
When the DMAC or the DTC*
2
is activated by a TXI
interrupt and transfers transmission data to TDR
1 MPB 0 R Multiprocessor Bit
This bit is not used in Smart Card interface mode.
0 MPBT 0 R/W Multiprocessor Bit Transfer
Write 0 to this bit in Smart Card interface mode.
Notes: 1. The write value should always be 0 to clear the flag.
2. The clearing conditions using the DTC are that DISEL bit be cleared to 0 and the
transfer counter value be other than 0.
3. To clear the flag by the CPU on the H8S/2215R, H8S/2215T, and H8S/2215C, reread
the flag after writing 0 to it.
