Reset and Enable Ports
Most System Generator blocks that include memory or storage provide options to expose the reset and clock enable
ports. If un-selected, these ports are automatically connected to the final hardware's global reset and clock enable or
DCM schemes. Exposing these ports on the System Generator block creates a condition where the block is reset or
enabled when either the global signals or the local signals assert TRUE. You should use these ports if greater control
over these functions is required in the DSP system.
