Cautions 1. Directly connect the IC (Internally Connected) pin to GND0, GND1, or GND2.
2. Keep the voltage at the AVDD, VDDPORT, and VDDPLL pins the same as that at the VDD pin.
3. Keep the voltage at the AVSS, GNDPORT, and GNDPLL pins the same as that at GND0, GND1,
or GND2.
4. Connect each of the REGOSC and REGCPU pins to GND via a 0.1
F capacitor.
