Question:
What are the notes for time settings (S3511/S3530/S3531)
Answer:
If time data is rewritten in a product with an alarm interrupt (S-3511/S-3530/S-3531), be sure to disable
the alarm interrupt before the time is set.
Reason: When data is written using real-time data access 2, registers for hours, minutes, and seconds
are reset (all “0”’s), and arbitrary hours, minutes, and seconds are then set. If the alarm is set for 0:00
a.m. and the alarm interrupt is enabled, when the time data is rewritten the registers are reset (all “0”’s)
to 0:00 a.m., the set alarm time, thereby causing an interrupt (INT).
