R/W Default
Description
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 by the status register_1 access
command. It is read-only and read-clear. When the flag is “1”, it must be
initialized.

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 orexceedsthe detection
voltage(VDET). This flag is read by the status register_1 access
command. It is read-only and read-clear. When the flag is “1”, it must be
initialized.

When the interrupt signal is output from the
pin. The INT2# flag is
INT1#
set to “1”, and uses the alarm interrupt function for an interrupt signal
output from the pin.

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
3.0 V).

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

This flag is used to set 12-hour or 24-hour expression.
0: 12-hour expression
12/24
RESET
1: 24-hour expression
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.
