PIO Controller A Multiplexing
If a signal name is listed 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.
