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.
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:INTAE
This flag is used to choose the state of INT terminal output with interrupt output set. Enable this flag after
setting alarm time that forms a meeting condition in the INT register:
0 : Alarm interrupt output is disabled.
1 : Alarm interrupt output is enabled.
B3:INTME
This flag is used to make the output of the INT terminal per-minute edge interrupt or per-minute steady
interrupt. To make the output per-minute steady interrupt, set "1" at INTME and INTFE .
0 : Alarm interrupt or selected frequency steady interrupt output
1 : Per-minute edge interrupt or per-minute steady interrupt output
B1:INTFE
This flag is used to make the output of the INT terminal per-minute steady interrupt output (a period of one
minute, 50% of duty) or selected frequency steady interrupt. Note that the INT 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
B4, B2 and B0: If having written contents, they are ignored. When they are read, "0" can be read from them.
