Bit 6—Transmit End (TEND): Indicates that when the last bit of a serial character was
transmitted, the SCFTDR2 did not contain valid data, so transmission has ended.
Bit 6: TEND
0
1
Bit 5—Transmit FIFO Data Empty (TDFE): Indicates that data is transferred from transmit
FIFO data register 2 (SCFTDR2) to transmit shift register (SCTSR), the quantity of data in
SCFTDR2 becomes less than the number of transmission triggers specified by the TTRG1 and
TTRG0 bits in FIFO control register 2 (SCFCR2), and writing the transmit data to SCFTDR2 is
enabled.
Bit 5: TDFE
0
1
Note: * Since SCFTDR2 is a 16-byte FIFO register, the maximum quantity of data which can be
written when TDFE is 1 is “16 minus the specified number of transmission triggers.” If an
attempt is made to write additional data, the data is ignored. The quantity of data in
SCFTDR2 is indicated by the upper 8 bits of SCFTDR2.
Description
Transmission is in progress.
TEND is cleared to 0 when data is written in SCFTDR2.
End of transmission.
TEND is set to 1 when the chip is reset or enters standby mode, TE is cleared to
0 in the serial control register (SCSCR2), or when SCFTDR2 does not contain
received data when the last bit of a one-byte serial character is transmitted.
Description
The quantity of transmit data written to SCFTDR2 is greater than the specified
number of transmission triggers.
TDFE is cleared to 0 when data exceeding the specified transmission trigger
number is written to SCFTDR2, and software reads 1 from TDFE and then writes
0 to TDFE.
The quantity of transmit data in SCFTDR2 is less than the specified number of
transmission triggers.*
TDFE is set to 1 at reset or at standby mode, or when the quantity of
transmission data in SCFTDR2 becomes less than the specified number of
transmission triggers as a result of transmission.
