The TxD pin is automatically
designated as the transmit data
output pin.
After the TE bit is set to 1, a frame
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.
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 DMAC or DTC
is activated by a transmit-data-
empty interrupt (TXI) request, and
data is written to TDR.
transmission:
transmission, set DDR for the port
corresponding to the TxD pin to 1,
clear DR to 0, then clear the TE bit
of 1s is output, and transmission is
enabled.
procedure:
To continue serial transmission,
To output a break in serial
in SCR to 0.
