*) Default settings: Default value means read / written values when the PON bit is set to “1” due to VDD
power-on from 0 volts.
* The D5 bit of the Alarm_W Hour Register represents WP/ A when the 12-hour mode is selected (0 for
a.m. and 1 for p.m.) and WH20 when the 24-hour mode is selected (tens in the hour digits).
* The Alarm_W Registers should not have any non-existent alarm time settings.
(Note that any mismatch between current time and preset alarm time specified by the Alarm_W registers
may disable the alarm interrupt circuit.)
* When the 12-hour mode is selected, the hour digits read 12 and 32 for 0 a.m. and 0 p.m., respectively.
(See "P12
Control Register 1 (ADDRESS Eh) (2) 12 /24: 12 /24-hour Mode Selection Bit")
* WW0 to WW6 correspond to W4, W2, and W1 of the day-of-week counter with settings ranging from (0, 0,
0) to (1, 1, 0).
* WW0 to WW6 with respective settings of 0 disable the outputs of the Alarm_W Registers.
