Cautions 1. The AVDD pin is multiplexed with an A/D converter power pin and a port power pin. In an applica-
tion where the noise generated from the microcontroller must be reduced, connect the AVDD pin
to a power supply of the same voltage as VDD.
2. The AVSS pin is multiplexed with an A/D converter ground pin and a port ground pin. In an
application where the noise generated from the microcontroller must be reduced, connect AVSS
pin to a ground line separate from VSS.
