Input Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
ANB3 — Analog input to ADC B, Channel 3.
V
REFLB
— Analog reference voltage low (ADC B).
After reset, the default state is GPIOC7.

Input Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
External Crystal Oscillator Input — This input can be connected to
an 8MHz external crystal. Tie this pin low if XTAL is being driven by
an external clock source.
After reset, the default state is GPIOD4.

Test Data Input — This input pin provides a serial input data stream
to the JTAG/EOnCE port. It is sampled on the rising edge of TCK
and has an on-chip pull-up resistor.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TDI.
