2.2 Status register
The status register is an 8-bit register which allows you to display and set various modes. The POWER
flag is read-only and others are read/write-enabled.

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 detection
voltage. When the flag is "1", you must send the reset command (or status register
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 pin (or INT2 pin) output with alarm
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 pin (or INT2 pin) 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 pin (or INT2 pin) 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 per-minute edge interrupt output
1 : Per-minute steady interrupt or selected frequency steady
interrupt output
