Management Requests are of different widths.
The AXI4-Lite bus uses 32 bits of data. The API issues multiple 32-bit writes up to the width of the Management Request. The AXI4-Lite writes are assembled by the secondary AXI4 to a single Management Request. The AXI4-Lite interface is a standard type. Refer to AXI4-Lite IPIF LogiCORE IP Product Guide (PG155).
Recommended: It is recommended to set the AXI4-Lite
frequency to at least 100 MHz.
Note:
AXI4-Lite imposes the following requirements when switching between
read and write:
- All outstanding write responses must have been received before issuing a read.
- All outstanding read responses must have been received before issuing a write.
