Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
ANB4 — Analog input to ADC B, Channel 4.
After reset, the default state is GPIOC12.
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.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
External Crystal Oscillator Output — This output connects the
internal crystal oscillator output to an external crystal.
External Clock Input — This pin serves as an external clock input.
After reset, the default state is GPIOD5.
Input,
internal
pull-up
enabled
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.
Output
tri-stated,
internal
pull-up
enabled
Test Data Output — This tri-stateable output pin provides a serial
output data stream from the JTAG/EOnCE port. It is driven in the
shift-IR and shift-DR controller states, and changes on the falling
edge of TCK.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TDO.
