The auto calendar function updates all dates, months, and years from January 1, 2001 to December 31, 2099.
The data format is BCD format. For example, a date register value of "0011 0001" indicates the 31st.
Note with caution that writing non-existent date data may interfere with normal operation of the calendar counter.
1) [ DAY ] register ( Reg 04 [h] )
This is the date counter.
Updating of this counter varies depending on the month.
A leap year is set whenever the year value is a multiple of four (such as 04, 08, 12, 88, 92, or 96). In
February of a leap year, the counter counts dates from "01," "02," "03," to "28," "29," "01," etc.
