   • Select the Memory.pvbus Slave Port line, and click Edit Connection....
   • Double click on the entry.

3. Select the Enable address mapping checkbox to activate the address text fields.
   The address mapping for the master port is shown on the left side of the Edit Connection dialog. Start, End, and Size are all editable. If one value changes, the other values are automatically updated if necessary. The equivalent LISA statement is displayed at the bottom of the Edit Connection dialog.
4. Enter a Start address of 0x00000000 and an End address of 0x10FFFFFF in the active left-hand side of the Edit Connection dialog. The Size of 0x11000000 is automatically calculated.
   This step maps the master port to the selected address range. If mapping the master port to a different address range on the slave port is required, select Enable slave port address range. Checking it makes the parameters for the slave port editable. The default values are the same as for the master port when the slave address range is enabled. Disabling the slave address range is equivalent to specifying the address range 0...size-1, and not the master address range. In this case, a slave port address range is not required, so deselect the Enable slave port address range checkbox.
