GNDA
4
-
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.

51
O
OD
An output that indicates the processor is in Hibernate mode.
72
I/O
OD
I²C module 0 clock.
65
I/O
OD
I²C module 0 data.
19
I/O
OD
I²C module 1 clock.
18
I/O
OD
I²C module 1 data.
LDO
7
-
Power Low drop-out regulator output voltage. This pin requires an
external capacitor between the pin and GND of 1 µF or
greater. When the on-chip LDO is used to provide power to
the logic, the LDO pin must also be connected to the VDD25
pins at the board level in addition to the decoupling
capacitor(s).
NMI
89
I
TTL
Non-maskable interrupt.
OSC0
48
I
Analog Main oscillator crystal input or an external clock reference
input.
OSC1
49
O
Analog Main oscillator crystal output. Leave unconnected when using
a single-ended clock source.
PA0

TTL
GPIO port A bit 1.
PA2
28
I/O
TTL
GPIO port A bit 2.
PA3
29
I/O
TTL
GPIO port A bit 3.
