2-2.Status register
The status register is an eight-bit register which allows you to display and set various modes. The POWER flag is read-only
and others are read/write-enabled.

Figure 10 Status register
B7:POWER
This flag turns to "1" if the power voltage detecting circuit operates during power-on or changes in
power voltage (below VDET). Once turning to "1", this flag does not turns back to "0" even when the
power voltage reaches or exceeds the detected voltage. When the flag is "1", you must send the reset
command and turn it to "0". It is a read-only flag.
B6:12/24
This flag is used to set 12-hour or 24-hour expression.
0 : 12-hour expression
1 : 24-hour expression
B5:INT1AE , B4:INT2AE
This flag is used to choose the state of INT1 terminal (or INIT2 terminal) output with interrupt output
set. Enable this flag after setting alarm time that forms a meeting condition in the INT1 register (or
INT2 register):
0 : Alarm interrupt output is disabled.
1 : Alarm interrupt output is enabled.
B3:INT1ME , B2:INT2ME
This flag is used to make the output of the INT1 terminal (or INT2 terminal) per-minute edge interrupt
or per-minute steady interrupt. To make the output per-minute steady interrupt, set "1" at INT1ME and
INT1FE (or INT2ME and INT2FE).
0 : Alarm interrupt or selected frequency steady interrupt output
1 : Per-minute edge interrupt or per-minute steady interrupt output
B1:INT1FE , B0:INT2FE
This flag is used to make the output of the INT1 terminal (or INT2 terminal) per-minute steady interrupt
output (a period of one minute, 50% of duty) or selected frequency steady interrupt. Note that the INT1
register (INT2 register) is considered as the data of frequency/duty if selected frequency steady
interrupt is chosen.
0 : Alarm interrupt or selected frequency steady interrupt output
1 : Per-minute edge interrupt or per-minute steady interrupt output
