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.
