3. Pin Assignments:

️· The document details the pin assignments for each package. A crucial note is that many pins are *relocated*, meaning they can perform multiple functions. This is controlled by the Extended Port Function Register (EPFR). The number after the underscore in the pin name indicates the relocated port number.

Key Notes & Important Considerations:

️· Relocated Pins: The use of the EPFR to configure relocated pins is essential.
️· Port Relocate Function: This function allows for flexibility in assigning functions to pins.
️· Internal Clock Accuracy: Refer to the specifications for accuracy of the built-in oscillators.
