= TIE = TEIE = 0). TSR, TDR, and SSR are reset. The states of the output pins during each mode
depend on the port settings, and the pins output a high-level signal after mode is cancelled and
then the TE is set to 1 again. If the transition is made during data transmission, the data being
transmitted will be undefined.
To transmit data in the same transmission mode after mode cancellation, set TE to 1, read SSR,
write to TDR, clear TDRE in this order, and then start transmission. To transmit data in a different
transmission mode, initialize the SCI first.
Figure 15.33 shows a sample flowchart for mode transition during transmission. Figures 15.34 and
15.35 show the pin states during transmission.
Before making the transition to module stop or software standby, stop all transmit operations (TE
