Are you sure you read '1' on reset input? Since it is stated that the input is debounced it seems to be inteded that it may be connected to some reset button that should be switch to high then pressed to trigger high active reset input.

The datasheet itself is not very comprehensive. it does not even contain information about energy consumption or how to access the eeprom
