(2) This instruction sets BIN values for each item.
(3) This instruction sets the year of four digits selected from 1980 to 2079 with the BIN value specified by
(4) This instruction sets the month selected from 1 to 12 (January to December) with the BIN value specified by
+1.

(5) This instruction sets the day selected from 1 to 31 (1st to 31st) for with the BIN value specified by
(6) This instruction specifies the following values at n so that the data to be compared can be specified.
The bit configuration specified at n is as follows.
This instruction specifies 0 at bits from 3rd to 14th.
The instruction will be non-conductive status without
specifying 0 regardless of the operation result.

If this instruction specifies 1 (on) at 15th bit, the
instruction compares S1 with the current date in
accordance with the bit condition specified at 0 to 2nd
bit.
(a) Date data to be compared (from 0 to 2nd bit)
• 0: Does not compare specified date data (year/month/day).
• 1: Compares specified date data (year/month/day).
(b) Operation data to be compared (15th bit)
• 0: Compares the date data specified by
• 1: Compares the date data specified by
