Serial Data Transmission (Asynchronous Mode): Figure 15.5 shows a sample flowchart for
serial transmission.
The following procedure should be used for serial data transmission.

The TxD pin is automatically
designated as the transmit data
output pin.
After the TE bit is set to 1, one
frame of 1s is output and
transmission is enabled.
write:
Read SSR and check that the
TDRE flag is set to 1, then write
transmit data to TDR and clear the
TDRE flag to 0.
procedure:
To continue serial transmission,
read 1 from the TDRE flag to
confirm that writing is possible,
then write data to TDR, and then
clear the TDRE flag to 0. Checking
and clearing of the TDRE flag is
automatic when the DTC is
activated by a transmit-data-empty
interrupt (TXI) request, and data is
written to TDR.
transmission:
To output a break in serial
transmission, set DDR for the port
corresponding to the TxD pin to 1,
clear DR to 0, then clear the TE bit
in SCR to 0.
