4 Pinout and Packaging

Each pin is controlled by the I/O Pin Controller (PORT) as a general purpose I/O and alternatively can be assigned to one of the peripheral functions: A, B, C, D, E, F, G, H, I, J, or K.

The following tables describe the peripheral signals multiplexed to the PORT I/O pins for each package.

The column “Reset State” indicates the reset state of the line with mnemonics:

"I/O" or "Function" indicates whether the I/O pin resets in I/O mode or in peripheral function mode
“I”/”O”/"Hi-Z" indicates whether the I/O is configured as an input, output or is tri-stated
“PU”/“PD” indicates whether pull up, pull down or nothing is enabled

Note: The Schematic Checklist chapter provides the user with the requirements regarding the different pin connections that must be considered before starting any new board design and information on the minimum hardware resources required to quickly develop an application.
