Figure 11 Status Register_1
B7: POC
This flag is set to “1” at power-on. Once this flag is set to “1”, it is not set to “0” even
when the power supply voltage reaches or exceeds the detection voltage (VDET). This
flag is read-only and can be read by the status register_1 access command. Once it is
read, it is automatically set to “0”. When the flag is “1”, it must be initialized. For the
method of initialization, refer to “Initialization at Power-on and Power-on Detector”.
B6: BLD
If the power supply voltage detector detects a voltage of detection voltage (VDET) or
less this flag is set to “1”, which enables the detection of a power supply voltage drop.
Once this flag is set to “1”, it is not set to “0” even when the power supply voltage
reaches or exceeds the detection voltage (VDET). This flag is read-only and can be
read by the status register_1 access command. Once it is read, it is automatically set
to “0”. When the flag is “1”, it must be initialized. For the method of initialization, refer
to “Initialization at Power-on and Power-on Detector”. and for the operation of the
power supply voltage detector, refer to “Power Supply Voltage Detector”.
B5, B4: INT2, INT1
When the interrupt signal is output from the INT pin using the alarm interrupt function,
for an interrupt set by INT1, the INT1 flag is set to “1”, and for an interrupt set by INT2,
the INT2 flag is set to “1”.
B3, B2: SC1, SC0
These flags configure a 2-bit SRAM type register that can be freely set by users. They
are read and written within the operating voltage range (1.3 to 5.5 V).
B1:
12/24
This flag is used to set 12-hour or 24-hour expression.
0: 12-hour expression
1: 24-hour expression
B0: RESET
By setting this bit to “1”, the internal IC is initialized. This is a write-only bit and is
always “0” when it is read. Be sure to write “1” to the reset flag when applying the
power supply voltage to the IC.
