Capture/Compare/PWM 0.TTLI/OCCP0
GPIO port D bit 5.TTLI/OPD5
96
The ground reference for the analog circuits (ADC, Analog
Comparators, etc.). These are separated from GND to minimize
the electrical noise contained on VDD from affecting the analog
functions.
Power-GNDA
97
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 748, regardless of system implementation.
