Figure 12.31 shows a sample flowchart for mode transition during reception.

Read TEND flag in SSR

TE = 0

Transition to software

standby mode, etc.

Exit from software

All data

transmitted?

TEND = 1

Yes

[1]

[2]

TE = 1

Initialization

[1]

Data being transmitted is

interrupted. After exiting software

standby mode, etc., normal CPU

transmission is possible by setting

TE to 1, reading SSR, writing TDR,

and clearing TDRE to 0, but note

that if the DTC has been activated,

the remaining data in DTCRAM will

be transmitted when TE and TIE

are set to 1.

[2]

If TIE and TEIE are set to 1, clear

them to 0 in the same way.

[3]

Includes module stop mode, watch

mode, subactive mode, and

subsleep mode.
