12.4.3 Reading each counter during the real-time counter operation
RC1YEAR) during real-time counter operation (RC1PWR = 1).

Sep 30, 2010
Set as follows when reading each counter (RC1SEC, RC1MIN, RC1HOUR, RC1WEEK, RC1DAY, RC1MONTH,
Note Be sure to confirm that RWST = 0 before setting STOP mode.
Caution Complete the series of operations for setting RWAIT to 1 to clearing RWAIT to 0 within 1
Remark
second.
If RWAIT = 1 is set, the operation of RC1SEC to RC1YEAR is stopped. If a carry occurs from
RC1SUBC while RWAIT = 1, one carry can be internally retained. However, if two or more
carries occur, the number of carries cannot be retained.
RC1SEC, RC1MIN, RC1HOUR, RC1WEEK, RC1DAY, RC1MONTH, and RC1YEAR may be read
in any sequence.
All the registers do not have to be set and only some registers may be read.
