(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. Counters
3.1 Clock counter (BANK 0, at 0h-5h)
*1) The “*” mark indicates data which are set to 0 for read cycle and not set for write cycle.
*2) Any carry to 1-second digits from the second counter is disabled when the WTEN bit (of the control register 1) is set to 0.
*3) Time digit display (BCD code):
Second digits : Range from 00 to 59 and carried to minute digits when incremented from 59 to 00.
Minute digits : Range from 00 to 59 and carried to hour digits when incremented from 59 to 00.
Hour digits
: Range as shown in the section on the 12/24 bit and carried to day and day-of-the-week digits when incremented from 11 p.m. to 12
a.m. or 23 to 00.
*4) 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.
