Note 1: Programmable pull-up resistors for port 0 are controlled in 4-bit units (P00 to 03, P04 to 07). *1: Connect the IC as shown below to minimize the noise input to the VDD1 pin. Be sure to electrically short the VSS1, VSS2, and VSS3 pins.

*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.

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after the instruction for starting the subclock oscillation circuit is executed and to the time interval that is required for the oscillation to get stabilized after the HOLD mode is reset (see Figure 4). Note : The components that are involved in oscillation should be placed as close to the IC and to one another as possible because they are vulnerable to the influences of the circuit pattern.
