Cautions 1. In normal operation mode, connect VPP pin directly to the VSS pin, or pull it down.
In a system where the internal flash memory is rewritten while mounted on board, pull the VPP
pin down.
When pulling down, connection via a 470 Ωor higher and 10 kΩor lower resistor is recommended.
2. Connect the AVDD pin directly to VDD.
3. Connect the AVSS pin directly to VSS.
