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-3511A 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 INT 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 INT 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"
INT register
: "8000h"
3.2 When the power voltage detecting circuits operates
The power voltage detecting circuit included in S-3511A 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., 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-3511A does not reach
any indefinite area during backup), you do not have to send the reset command.
