All data transmitted?
Read TDRE flag in SSR
Start transmitting
Write transmit data in TDR
and set MPBT bit in SSR
Clear TDRE flag to 0
Output break signal?
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.
Also set the MPBT flag to 0 or 1 in
SSR. Finally, 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.
To output a break signal at the end of
serial transmission:
set the DDR bit to 1 and clear the DR
bit to 0, then clear the TE bit to 0 in
SCR.
