• Reception
Rev.7.00 Dec. 24, 2008 Page 446 of 698
REJ09B0074-0700
Receive operation should be stopped (by clearing RE to 0) before making a module stop mode,
software standby mode, watch mode, subactive mode, or subsleep mode transition. RSR, RDR,
and SSR are reset. If a transition is made without stopping operation, the data being received
will be invalid.
To continue receiving without changing the reception mode after the relevant mode is cleared,
set RE to 1 before starting reception. To receive with a different receive mode, the procedure
must be started again from initialization.
Figure 12.42 shows a sample flowchart for mode transition during reception.
