Section 16 Serial Communication Interface with FIFO (SCIF)
Bit 5—Transmit FIFO Data Empty (TDFE): Indicates that data has been transferred from
SCFTDR2 to SCTSR2, the number of data bytes in SCFTDR2 has fallen to or below the transmit
trigger data number set by bits TTRG1 and TTRG0 in the FIFO control register (SCFCR2), and
new transmit data can be written to SCFTDR2.

*
As SCFTDR2 is a 16-byte FIFO register, the maximum number of bytes that can be
written when TDFE = 1 is 16 - (transmit trigger set number). Data written in excess of
this will be ignored.
The number of data bytes in SCFTDR2 is indicated by the upper bits of SCFDR2.
Description
A number of transmit data bytes exceeding the transmit trigger set number
have been written to SCFTDR2
[Clearing conditions]
•
•
The number of transmit data bytes in SCFTDR2 does not exceed the
transmit trigger set number
[Setting conditions]
•
•
When transmit data exceeding the transmit trigger set number is written
to SCFTDR2 after reading TDFE = 1, and 0 is written to TDFE
When transmit data exceeding the transmit trigger set number is written
to SCFTDR2 by the DMAC
Power-on reset or manual reset
When the number of SCFTDR2 transmit data bytes falls to or below the
transmit trigger set number as the result of a transmit operation*
