Initialization at Power-on and Power-on Detector
When power is applied to this IC, status register_1 is set to “80h” (bit 7 (POC flag) of status register_1 is set
to “1”) by the power-on detector and a 1 Hz clock is output from the INT pin
*1. This function is provided to
adjust the oscillation frequency. In normal use, the IC must be initialized at power-on. Initialization is
performed by writing “1” to bit 0 (RESET flag) of status register_1.
Also, the IC must be initialized when the POC flag is set to “1”. After initialization, the POC flag is set to “0”.
For normal operation of the power-on detector, first hold the IC power supply voltage at 0 V and then
increase it.
*1. A 1 Hz clock may not be output depending on the state in which the power supply voltage is applied.
In this case, set the 1 Hz output using status register_2 and INT1 register_1.
Register State After Initialization
The state of each register after initialization is as follows.
Real-time data register:
00 (year), 01 (month), 01 (day), 0 (day of week), 00 (hour), 00 (minute),
00 (second)
Status register_1:
“0h
0b” (B3, B2, and B1 are user setting data.)
Status register_2:
“00h”
INT1 register_1:
“00h”
INT1 register_2:
“00h”
Clock adjustment register: “00h”
Free register:
“00h”
