Be sure to electrically short the VSS1, VSS2, and VSS3 pins. LSI VDD1 Power supply For backup *2 VDD2 VDD3 VSS1 VSS2 VSS3 *2: The internal memory is sustained by VDD1. If none of VDD2 and VDD3 are backed up, the high level output at the ports are unstable in the HOLD backup mode, allowing through current to flow into the input buffer and thus shortening the backup time. Make sure that the port outputs are held at the low level in the HOLD backup mode.
