Note 1 Programmable pull-up resisters of Port 0 can be attatched in nibble units (P00-03, P04-07).
* Note 1: Connect as follows to reduce noise on VDD and increase the back-up time.
VSS1, and VSS2 must be connected together and grounded.
*Note 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.

*The oscillation stabilizing time is a period until the oscillation becomes stable after executing the instruction which starts the
sub-clock oscillation or after releasing the HOLD mode. (Refer to Figure4)
