Figure 5-2 Configuration interface timing specification 
 
The POR configuration signals (POR_SIGNALS) listed in Table 5-6 are loaded into the appropriate 
internal configuration registers of the router after RST is de-asserted. To make sure that the POR 
configuration signal values are loaded properly they should be held stable for at least three CLK 
cycles following RST being de-asserted.  The status output STAT_MUX_OUT is driven on the fourth 
CLK 
cycle after RST is de-asserted.   
See section 6.3 for information on the operation of the status/power on configuration interface and 
section 10.5 for timing details. 
5.6  RESET CONFIGURATION SIGNALS 
The Reset Configuration signals are listed in Table 5-6. These signals are input on STAT_MUX_OUT 
after reset to initialise the router.  They are not used at any other time except immediately after reset.  
The Reset Configuration signals set relevant bits in the configuration registers (see section 9). 
Following reset the values of these signals are synchronously loaded into the router. The timing of the 
Reset Configuration signals is illustrated in Figure 6-7.
