Default Settings *)
*) Default settings: Default value means read / written values when the PON bit is set to “1” due to VDD
power-on from 0 volts.
* 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.
