Register Mapping
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.
