Before making the transition to module stop state or software standby mode, stop the transmit
operations (TE = TIE = TEIE = 0). TSR, TDR, and SSR are reset. The states of the output pins
during module stop state or software standby mode depend on the port settings, and the pins
output a high-level signal after mode cancellation. 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 the TE bit 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 16.34 shows a sample flowchart for mode transition during transmission. Figures 16.35 and
16.36 show the port pin states during mode transition.
Before making the transition from the transmission mode using DTC transfer to module stop state
or software standby mode, stop all transmit operations (TE = TIE = TEIE = 0). Setting the TE and
TIE bits to 1 after mode cancellation sets the TXI flag to start transmission using the DTC.
(2)
Before making the transition to module stop state or software standby mode, stop the receive
operations (RE = 0). RSR, RDR, and SSR are reset. If transition is made during data reception, the
data being received will be invalid.
To receive data in the same reception mode after mode cancellation, set the RE bit to 1, and then
start reception. To receive data in a different reception mode, initialize the SCI first.
