Transmitting Serial Data (Synchronous Mode)
Figure 13.16 shows a sample flowchart for transmitting serial data and indicates the procedure
to follow.

1. SCI initialization: the transmit data output function
2. SCI status check and transmit data write: read
3. To continue transmitting serial data: after checking
of the TxD pin is selected automatically.
SSR, check that the TDRE flag is 1, then write
transmit data in TDR and clear the TDRE flag to 0.
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.
