Spartan-6 - How long after loading a command on the ICAP can CE be deasserted?
The ICAP control logic I use follows the User Guide recommendations, but the command loaded does not take effect.
What is the issue here? How long after loading a command on the ICAP can CE be deasserted?
After loading a command on the ICAP interface the CE must be asserted for two clock cycles. If CE is deasserted within two clock cycles of the command, the command might not execute.
