Default settings:
Default value means read / written values when the XSTP bit is set to “1” due to VDD
power-on from 0v or oscillation stopping
*
Time digit display (BCD format) as follows:
The second digits range from 00 to 59 and are carried to the minute digit in transition from 59 to 00.
The minute digits range from 00 to 59 and are carried to the hour digits in transition from 59 to 00.
The hour digits range as shown in "P12
Control Register 1 (ADDRESS Eh) (2) /12
24: /12-24-hour
Mode Selection Bit" and are carried to the day-of-month and day-of-week digits in transition from
PM11 to AM12 or from 23 to 00.
*
Any writing to the second counter resets divider units of less than 1 second.
*
Any carry from lower digits with the writing of non-existent time may cause the time counters to
malfunction.
Therefore, such incorrect writing should be replaced with the writing of existent time
data.

Default settings:
Default value means read / written values when the XSTP bit is set to “1” due to VDD
power-on from 0v or oscillation stopping
*
The day-of-week counter is incremented by 1 when the day-of-week digits are carried to the
day-of-month digits.
*
Day-of-week display (incremented in septimal notation):
(W4, W2, W1) = (0, 0, 0)
→ (0, 0, 1)→…→(1, 1, 0) → (0, 0, 0)
*
Correspondences between days of the week and the day-of-week digits are user-definable
(e.g. Sunday = 0, 0, 0)
*
The writing of (1, 1, 1) to (W4, W2, W1) is prohibited except when days of the week are unused.
