Pin Configuration

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

2. AVDD pin should be connected to VDD.

3. AVSS pin should be connected to VSS.

Remark:

When these devices are used in applications, that require reduction of the noise, generated

from inside the microcontroller, the implementation of noise reduction measures, such as

connecting the VSS0 and VSS1 to different ground lines, is recommended.
