*Note 1: Connect as follows to reduce noise on VDD.
VSS1, VSS2 and VSS3 must be connected together and grounded.
*Note 2: The power supply for the internal memory is VDD1 but it uses the VDD3 as the power supply for ports.
When the VDD3 is not backed up, the port level does not become “H” even if the port latch is in the “H” level.
Therefore, when the VDD3 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 VDD3 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.
