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 AH20 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 AW0 through AW6 is set to 0.
*9) Each of the AW0 through AW6 corresponds to the day-of-the-week counter such as (W4, W2, W1)=(0, 0, 0) through (1, 1, 0). Designation of day-of-
the-week and AW0 through AW6 in the above table is one example.

Bits for selecting the interrupt cycle and output mode at the INTR pin *1
*1) (CT3 to CT0)
The CT3 to CT0 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 CT3 bit is set to 0) and the level mode (when the CT3 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)”.
