5 Package and Pinout

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, and D.

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

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

• “PIO”/“Signal” indicates whether the PIO line resets in I/O mode or in peripheral function mode
  • If “PIO” is mentioned, the PIO line is maintained in a static state as soon as the reset is released. As a result, the bit corresponding to the PIO line in the PIO_PSR (Peripheral Status Register) resets low.
  • If a “signal” name is mentioned, the PIO line is assigned to this function and the corresponding bit in the PIO_PSR resets high. This is the case of pins controlling memories, in particular the address lines, which require the pin to be driven as soon as the reset is released.
• “I”/“O”/“Hi-Z” indicates whether the I/O is configured as an input, output, or tri-stated.
• “PU”/“PD” indicates whether the pull up, pull down, or nothing is enabled.
• “ST” indicates if Schmitt Trigger is enabled.
