PUSHBUTTON TIMING DIAGRAMS Figure 4
If during any pushbutton activity the STR input is activated, pushbutton operation will be suspended until
the storage of EEPROM has been completed. Once complete, pushbutton inputs, if still active, will
resume from the point of suspension. Command initiated storage operations will require a minimum of
4 ms to complete the storage operation. This 4 ms is measured from the rise of STR input (see Figure 5).
For applications not requiring or using the nonvolatile memory feature of the DS1809, it is recommended
that the STR input be connected to GND.
