Buffer Type^a Description
TTL
UART module 1 transmit. When in IrDA mode, this
signal has IrDA modulation.

Bidirectional differential data pin (D- per USB
specification) for USB0.
Bidirectional differential data pin (D+ per USB
specification) for USB0.
9.1-kΩ resistor (1% precision) used internally for
USB analog circuitry.
Power source for the Hibernation module. It is
normally connected to the positive terminal of a
battery and serves as the battery
backup/Hibernation module power-source supply.
Positive supply for I/O and some logic.

Analog
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 Table 25-2 on page 1099, regardless
of system implementation.
Positive supply for most of the logic function,
including the processor core and most peripherals.
The voltage on this pin is 1.3 V and is supplied by
the on-chip LDO. The VDDC pins should only be
connected to the LDO pin and an external capacitor
as specified in Table 25-6 on page 1104.
This input provides a reference voltage used to
specify the input voltage at which the ADC converts
to a maximum value. In other words, the voltage
that is applied to VREFA is the voltage with which
an AINn signal is converted to 1023. The VREFA
input is limited to the range specified in Table
25-23 on page 1111 .
