Reception: Before making the transition to module stop, software standby, watch, subactive, or
subsleep mode, stop reception (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 RE to 1, and then start
reception. To receive data in a different reception mode, initialize the SCI first.
Figure 16.24 shows a sample flowchart for mode transition during reception.
