7. Memory Subsystem Register Descriptions
When you request a command and status register (CSR) access through AXI-Lite interface, the request address is decoded based on the address maps shown in this section and routed to the correct destination interface.
The AXI-Lite interface does not support unaligned access and any requests with unaligned access are translated to fully aligned access, ignoring the lower 2 address bits of the requests.
Write operations to a read-only register field have no effect. Read operations that address a Reserved register return all zeroes. Write operations to reserved registers have no effect. Accesses to registers that do not exist in your IP core variation, or to register bits that are not defined in your IP core variation, return values of all zeroes.
