11.4.2 Rewriting each counter during clock operation
RC1YEAR) during clock operation (RC1PWR = 1).

Set as follows when rewriting 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
berewrite in any sequence.
All the registers do not have to be set and only some registers may be read.
