2-4.Test flag
The test flag is a one-bit register which is assigned to MSB of the second data of the real-time data register. If a transferred
data is considered as the test mode starting data due to the receiving of the test mode starting data or noises, "1" is set.
When "1" is set, you must send the test mode ending command or reset command.

Initialization
Note that S-3530A has different initializing operations, depending on states.
3-1.When power is turned on
When power is turned on, the status register is set to "82h" and the INT1 register to "8000h" by the power-on detecting
circuit. In other words, "1" is sets at the bit 7 (POWER flag) of the status register and the clock of 1HZ is output from the INT1
terminal. This is provided to adjust oscillating frequencies. In normal use, the reset command must be sent when power is
turned on.
Real-time data register :
00 (year), 01 (month), 01 (day), 0 (day of week), 00 (hour), 00 (minute), 00 (second)
Status register
:
"82h"
INT1 register : "8000h"
INT2 register : "0000h"
3-2.When the power voltage detecting circuits operates
The power voltage detecting circuit included in S-3530A operates and sets "1" at the bit 7 (POWER flag) of the internal status
register when power is turned on or power voltage is reduced. Once "1" is set, it is held even after the power voltage gets
equal to or higher than the detected power voltage. When the flag has "1", you must send the reset command from CPU and
initialize the flag. At this point, other registers does not change.
However, if the POWER flag has "0" during the power-on reset of CPU (S-3530A does not reach any indefinite area during
backup), you do not have to send the reset command.
3-3.When the reset command is received
When the reset command is received, each register turns as follows:
Real-time data register :
00 (year), 01 (month), 01 (day), 0 (day of week), 00 (hour), 00 (minute), 00 (second)
Status register
:
"00h"
INT1 register : "0000h"
INT2 register : "0000h"
Set to frequency
duty mode
