) Default settings: Default value means read/written values when the XSTP bit is set to “1” due to power-on from 0 volts or supply voltage drop.
· The D5 bit represents DP/A when the 12-hour mode is selected (0 for a.m. and 1 for p.m.). and DH
20
when the 24-
hour mode is selected (tens in the hour digits).
· The Alarm_D 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_D registers may disable the alarm 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 “2.1-2
12/24: 12-/24-hour Mode Selection Bit”).
