27.6
Each I/O line controlled by the PIO Controller is associated with a bit in each of the PIO Controller User Interface registers.
Each register is 32 bits wide. If a parallel I/O line is not defined, writing to the corresponding bits has no effect. Undefined
bits read zero. If the I/O line is not multiplexed with any peripheral, the I/O line is controlled by the PIO Controller and
PIO_PSR returns 1 systematically.
