PWM 2. This signal is controlled by PWM Generator 1.
87
GND
-
Power Ground reference for logic and I/O pins.
88
VDD25
-
Power Positive supply for most of the logic function, including the
processor core and most peripherals.

I/O
TTL
GPIO port B bit 5.
91
C1-
I
Analog Analog comparator 1 negative input.
PB4
I/O
TTL
GPIO port B bit 4.
92
C0-
I

93
VDD
-
Power Positive supply for I/O and some logic.
94
GND
-
Power Ground reference for logic and I/O pins.
95
ADC7
I
Analog Analog-to-digital converter input 7.
96
ADC6
I
Analog Analog-to-digital converter input 6.
GNDA
97
-
Power 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.
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 628, regardless of system implementation.
99
ADC5
I
Analog Analog-to-digital converter input 5.
100
ADC4
I
Analog Analog-to-digital converter input 4.
a. The TTL designation indicates the pin has TTL-compatible voltage levels.
