Cautions 1. Connect IC (internally connected) pin directly to VSS0.

2. AVSS pin should be connected to VSS0.

Remark When the circuit is used in an application where the noise generated from the inside of the microcontroller

needs to be reduced, take countermeasures against noise such as supplying power to VDD0 and VDD1

separately and connecting VSS0 and VSS1 to the ground line separately.
