23 * \brief The ParamWBAccess enum
\r
24 * Read means that the block setup the value of this parameter and it is possible to
\r
25 * to read that value from outside the FPGA (via the wrapper of the wishbone). Thus,
\r
26 * from the block point of view, the parameter corresponds to an output port.
\r
27 * Write means that it is possible to setup the value of this paramter from outside the FPGA (via
\r
28 * the wrapper of the wishbone) so that the block can read that value. Thus,
\r
29 * from the block point of view, the parameter corresponds to an input port.
