2.4 Alarm registers for day-of-the-week, 1-minute, 10-minute, 1-hour, 10-hour (BANK1, at 0h-5h)
*
1) The “
” mark in the above table indicates data which are set to 0 for read cycle and not set for write cycle.
*
2) 10-hour time digit indicates AP/A and AH
20
with 12-hour and 24-hour time system respectively.
*
3) Make sure set an actual time-data to the alarm registers when the alarm function is activated as any imaginary alarm-data will never be match with
the actual time.
*
4) The INTR pin can output matched alarm interruption when the ALC bit is set 0 and halt output when the ALC bit is set to 1.
*
5) The alarm function is disabled when the ALE bit is set 0 and is enables when the ALE bit is set 1.
*
6) Examples of setting alarm time
*
7) Hour digits show “12” and “32” when the time is AM 00:00 and PM 00:00 respectively in the 12-hour system.
*
8) No alarm interruption is output when all the bit from AW
0
through AW
6
is set to 0.
*
9) Each of the AW
0
through AW
6
corresponds to the day-of-the-week counter such as (W
4
, W
2
, W
1
)=(0, 0, 0) through (1, 1, 0). Designation of day-of-
the-week and AW
0
through AW
6
in the above table is one example.

1) (CT
3
to CT

)
The CT
3
to CT
0
bits are used to select the interrupt cycle and output mode at the INTR pin. There are two interrupt modes selectable: the pulse
mode (when the CT
3
bit is set to 0) and the level mode (when the CT
3
bit is set to 1). The interrupt cycle and output mode at the INTR pin are shown
in detail in the section on the CTFG bit in “2.1 Control Register 1 (at Eh)”.
