R/W* Transmit FIFO Data Empty
Description
Indicates that data has been transferred from SCFTDR
to SCTSR, the number of data bytes in SCFTDR has
fallen to or below the transmit trigger data number set
by bits TTRG1 and TTRG0 in SCFCR, and new
transmit data can be written to SCFTDR.
0: A number of transmit data bytes exceeding the

Note: As SCFTDR is a 64-byte FIFO register, the

not exceed the transmit trigger set number (Initial
value)
When transmit data exceeding the transmit trigger
set number is written to SCFTDR after reading
TDFE = 1, and 0 is written to TDFE
When transmit data exceeding the transmit trigger
set number is written to SCFTDR by the DMAC
Power-on reset or manual reset
When the number of SCFTDR transmit data bytes
falls to or below the transmit trigger set number as
the result of a transmit operation*
maximum number of bytes that can be written
when TDFE = 1 is 64 - (transmit trigger set
number). Data written in excess of this will be
ignored.
SCTFDR indicates the number of data bytes
transmitted to SCFTDR.
