VSS1, VSS2, and VSS3 must be connected together and grounded. LSI VDD1 Power supply Back-up capacitors *2 VDD2 VDD3 VSS1 VSS2 VSS3 *2: The power supply for the internal memory is VDD1 but it uses the VDD2 as the power supply for ports. When the VDD2 is not backed up, the port level does not become “H” even if the port latch is in the “H” level. Therefore, when the VDD2 is not backed up and the port latch is “H” level, the port level is unstable in the HOLD mode, and the back up time becomes shorter because the through current runs from VDD to GND in the input buffer. If VDD2 is not backed up, output “L” by the program or pull the port to “L” by the external circuit in the HOLD mode so that the port level becomes “L” level and unnecessary current consumption is prevented.
