Transmitting: Figure 10.8 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?

TEND = 1?

Read bit TEND in SSR

Break output?

Set PDR = 0 and PCR = 1

Clear bit TE in SCR3 to 0

End

Read the serial status register (SRR),

and after confirming that bit TDRE = 1,

write transmit data in the transmit data

TDR, TDRE is automatically cleared to 0.

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.

To output a break signal when transmission

ends, first set the port values PCR = 1 and

PDR = 0, then clear bit TE in SCR3 to 0.

Yes
