• Transmitting Serial Data (Synchronous Mode): Figure 13.16 shows a sample flowchart for
In transmitting serial data, the SCI operates as follows.
• The SCI monitors the TDRE flag in SSR. When the TDRE flag is cleared to 0, the SCI

SCI initialization: the transmit data output
function of the TxD pin is selected
automatically.
SCI status check and transmit data write:
read SSR, check that the TDRE flag is 1,
then write transmit data in TDR and clear
the TDRE flag to 0.
To continue transmitting serial data: after
checking that the TDRE flag is 1, indicating
that data can be written, write data in TDR,
then clear the TDRE flag to 0. When the
DMAC is activated by a transmit-data-empty
interrupt request (TXI) to write data in TDR,
the TDRE flag is checked and cleared
automatically.
