(For read/write) Day-of-the-week counter
*1) The “*” mark indicates data which are set to 0 for read cycle and not set for write cycle.
*2) Day-of-the-week digits are incremented by 1 when carried to 1-day digits.
*3) Day-of-the-week digits display (incremented in septimal notation):
(W4, W2, W1)=(000)
(001) (110) (000)
The relation between days of the week and day-of-the-week digits is user changeable (e.g. Sunday=000).
*4) The (W4, W2, W1) should not be set to (111).
3.2 Day-of-the-week counter (BANK 0, at 6h)
3.3 Calendar counter (BANK 0, at 8h-Dh)
*1) The “*” mark indicates data which are set to 0 for read cycle and not set for write cycle.
*2) The automatic calendar function provides the following calendar digit displays in BCD code.
Day digits
: Range from 1 to 31 (for January, March, May, July, August, October, and December).
Range from 1 to 30 (for April, June, September, and November).
Range from 1 to 29 (for February in leap years).
Range from 1 to 28 (for February in ordinary years).
Carried to month digits when cycled to 1.
Month digits : Range from 1 to 12 and carried to year digits when cycled to 1.
Year digits : Range from 00 to 99 and counted as 00, 04, 08, ..., 92, and 96 in leap years.
*3) Any registered imaginary time should be replaced with actual time as carrying to such registered imaginary time digits from lower-order ones cause
the clock counter to malfunction.
