transmit operations are performed until there is no transmit data left in SCFTDR. When the
number of transmit data bytes in SCFTDR falls to or below the transmit trigger number set in
SCFCR, the TDFE flag is set. If the TIE bit in SCSCR is set to 1 at this time, a transmit-FIFO-
data-empty interrupt (TXI) request is generated. If and external clock is specified, the SCIF
outputs data in synchronization with the input clock. Serial transmit data is output in order
from LSB to MSB from the TxD pin.
present, the data is transferred from SCFTDR to SCTSR, the stop bit is sent, and then serial
transmission of the next frame is started.
If there is no transmit data, the TEND flag in SCFSR is set to 1, the stop bit is sent, and then
the state of the TxD pin is held.
