DDR SDRAM needs to cross clock domains when reading data, but not when writing data. How can this be explained? Because when writing data, both the data and the accompanying clock are sent by the FPGA...
I can't find how to read and write SFR directly through the address of SFR. For example, I get an address of 0x80, which is the address of an SFR. How can I write a byte to this address or read the co...
