I am using the native interface of the HPC for a DDR external memory.The HPC is set to half rate and I set the local_size to a hard coded 1 for a burst length of four. It is unclear to me about the use of the local interface pins. When writing a burst of data, I assume that I apply the address on the local_address pins, and assert local_write_req. When local_wdata_req asserts, I apply my data. What I don't get is this: When local_wdata_req stays asserted, when do I update the local_address? Do I update it every clock cycle are every 4 clock cycles? Thanks in advance for your consideration.
