2.4 Test flag
The test flag is a 1-bit register which is assigned to MSB of the second data of the real-time data
register. If transferred data is considered as the test mode starting command due to the receiving of the
test mode starting command or noises, "1" is set. When "1" is set, you must send the test mode ending
command or reset command.
3. 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 1 Hz is output from the INT1 pin. 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 detection voltage, i.e., the power voltage
detector threshold. 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.
