How to use the external clock to write to the CY7C68013A？
I use the FPGA to generate the clock for communicating with the CY7C68013A with the same code which is usable in the internal clock . But with the external clock , FPGA can not write the data to the FIFO of the CY7C68013A anymore. The flag of empty is always low. I do not know which part of the system is wrong , can you give me some advice?
