Description
Transmit FIFO Data Empty
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

Break Detect
Indicates that a receive data break signal has been
detected.
0: A break signal has not been received

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*
Power-on reset or manual reset
When 0 is written to BRK after reading BRK = 1
When data with a framing error is received, followed
by the space "0" level (low level ) for at least one
frame length
