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 specified 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. Note that the pull-up resistor is also enabled in this case.
