GNDA
97
-
Power The ground reference for the analog circuits ( Analog Comparators,
etc.). These are separated from GND to minimize the electrical
noise contained on VDD from affecting the analog functions.
VDDA
98
-
Power The positive supply for the analog circuits (ADC, Analog
Comparators, etc.). These are separated from VDD to minimize
the electrical noise contained on VDD from affecting the analog
functions. VDDA pins must be supplied with a voltage that meets
the specification in “Recommended DC Operating
Conditions” on page 541, regardless of system implementation.
