I
Analog Analog comparator 1 negative input.
PB4
I/O
TTL
GPIO port B bit 4.
92
C0-
I
Analog Analog comparator 0 negative input.
93
VDD
-
Power Positive supply for I/O and some logic.
94
GND
-
Power Ground reference for logic and I/O pins.
95
PD4
I/O
TTL
GPIO port D bit 4.
96
PD5
I/O
TTL
GPIO port D bit 5.
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 560, regardless of system implementation.
99
PD6
I/O
TTL
GPIO port D bit 6.
PD7
100
C0o
I/O
TTL
GPIO port D bit 7.
O
TTL
Analog comparator 0 output.
a. The TTL designation indicates the pin has TTL-compatible voltage levels.
