6 Package and Pinout

In the tables that follow, 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 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 register PIO_PSR (Peripheral Status Register) resets low.

If a signal name is mentioned in the “Reset State” column, the PIO line is assigned to this function and the corresponding bit in 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”

Indicates whether the signal is input or output state.

• “PU” / “PD”

Indicates whether pullup, pulldown, or nothing is enabled.

• “ST”

Indicates if Schmitt Trigger is enabled.
