4.1.8.3. Calculating the Address Span Extender Slave Address

The diagram describes how Platform Designer calculates the slave address. In this example, the address span extender is configured with a 28-bit address space for slaves. The upper 2 bits [27:26] are used to select the control registers.

The lower 26 bits ([25:0]) originate from the address span extender's data port, and are the offset into a particular window.
