Transmitting: Figure 10.14 shows a typical flow chart for data transmission. After SCI3

initialization, follow the procedure below.

Start

Read bit TDRE in SSR

TDRE = 1?

Write transmit data in TDR

Continue data transmission?

Read bit TEND in SSR

TEND = 1?

Write 0 to bit TE in SCR3

End

Yes

Read the serial status register (SSR),

and after confirming that bit TDRE = 1,

write transmit data in the transmit

data register (TDR).

When data is written to TDR, TDRE is

automatically cleared to 0.

If clock output has been selected, after

data is written to TDR, the clock is

output and data transmission begins.

To continue transmitting data, first read

TDRE to confirm that it is set to 1, indicating

that data writing is enabled; then write the

next data to TDR. When data is written to

TDR, TDRE is automatically cleared to 0.
