(6) Voltage Detector
The S-3510 series incorporates a voltage detector that performs sampling once a second for 62.5 msec.
When the supply voltage goes below the detection voltage, the BLD latch-up circuit latches
“
H,
”
and stops sampling.
[IMPORTANT]
The BLD flag can read 1 when the supply voltage increases and the first read is executed. After that, however, sampling is
permitted. Therefore, when the next read is performed after sampling of the detector, the BLD flag is reset. Refer to the
timing charts shown below:
When the CS is turned to “H,” the output of the latch-up circuit is transmitted to the shift register only when the subsequent
command is the READ command.
Reading the BLD bit allows the decrease in the voltage to be monitored.
If the CS is turned to “L” after completing the read, sampling restarts. That is, once a decrease in the voltage is detected,
detection is not performed and the status is kept “H” as long as an initialization is not performed or a READ command is not
sent.
