Note 1Attachment of Port0 programmable pull-up resistors is controllable in nibble units (P00-03, P04-07). * 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 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) (Notes) * Since the circuit pattern affects the oscillation frequency, place the oscillation-related parts as close to the oscillation pins as possible with the shortest possible pattern length.
