Cautions 1. The AV
DD
pin functions as both an A/D converter power supply and a port power supply. When
the
μ
PD78064B is used in applications where the noise generated inside the microcontroller
needs to be reduced, connect the AV
DD
pin to another power supply which has the same potential
as V
DD
.
2. The AV
SS
pin functions as both an A/D converter ground and a port ground. When the
μ
PD78064B
is used in applications where the noise generated inside the microcontroller needs to be
reduced, connect the AV
SS
pin to another ground line than V
SS
.
