1.4.4 Initialization Client

The Flash Memory System Builder initializes all the clients with the data stored in the Flash Memory when the system is powered-up. You must assert the INIT_POWER_UP signal to 'High' to power up the system. You can use the Initialization Client to set initial values of the RAM/FIFO (such as a table or list of filter coefficients, MAC addresses, etc.) and ROM emulation.
