Write transmit data to TDR
Clear TE bit in SCR3 to 0
Read TDRE flag in SSR
Read TEND flag in SSR
All data transmitted?

Read SSR and check that the TDRE flag is
set to 1, then write transmit data to TDR.
When data is written to TDR, the TDRE flag
is automatically cleared to 0 and clocks are
output to start the data transmission.
To continue serial transmission, be sure to
read 1 from the TDRE flag to confirm that
writing is possible, then write data to TDR.
When data is written to TDR, the TDRE flag
is automatically cleared to 0.
