Cautions 1. Connect directly the IC (Internally Connected) pin to VSS.
2. The AVDD pin functions as both an A/D converter power supply and a port power supply. When
the µPD78064B(A) is used in applications where the noise generated inside the microcontroller
needs to be reduced, connect the AVDD pin to another power supply which has the same
potential as VDD.
3. The AVSS pin functions as both an A/D converter ground and a port ground. When the
µPD78064B(A) is used in applications where the noise generated inside the microcontroller
needs to be reduced, connect the AVSS pin to another ground line than VSS.
