Set the TxD pin using the PFC.
After the TE bit is set to 1, 1 is
output for one frame, and
transmission is enabled. However,
data is not transmitted.
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, first clear the port
data register (DR) to 0, then clear
the TE bit to 0 in SCR and use the
PFC to select the TxD pin as an
output port.
