In order that IC protection is assured, please make sure that a diode is connected between the battery and the VDD. If the diode is not connected and the battery polarity was inverted, then the IC will fail. 2. In order to avoid unexpected programming, we suggest PGM pin connects with ground (VSS) to avoid PGM pin changed to “High level” and cause into “programming mode”.
