Figure 6-7 Reset configuration interface timing specification

The POR configuration signals (POR_SIGNALS) listed above are loaded into the appropriate internal configuration registers of the router on the first rising edge of the system clock, CLK, after RSTN is de- asserted. To make sure that the POR configuration signal values are loaded properly STATMUXOUT inputs must be stable from end of reset (rising edge of RSTN) till 4 CLK periods after the end of reset.
