Before specifying the module stop state or making a transition to software standby mode, stop the
transmit operations (TE = TIE = TEIE = 0). TSR, TDR, and SSR are reset. The states of the output
pins in the module stop state or in software standby mode depend on the port settings, and the pins
output a high-level signal after 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 cancellation of the power-down state, 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 14.34 shows a sample flowchart for transition to software standby mode during
transmission. Figures 14.35 and 14.36 show the port pin states in transition to software standby
mode.
Before specifying the module stop state or making a transition to software standby mode from the
transmission mode using DTC transfer, stop all transmit operations (TE = TIE = TEIE = 0).
Setting the TE and TIE bits to 1 after cancellation sets the TXI flag to start transmission using the
DTC.

Before specifying the module stop state or making a transition to 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 cancellation of the power-down state, set the RE
bit to 1, and then start reception. To receive data in a different reception mode, initialize the SCI
first.
Figure 14.37 shows a sample flowchart for transition to software standby mode during reception.
