See section 6.2 for information on the operation of the time-code interface and section 10.4 for timing 
details.

Select the error indication status signals to be 
output on STAT_MUX_OUT as defined in 
Table 6-1. 
These inputs should be driven or pulled up or 
down (e.g. 4k7 
Ω) depending on what 
information is required from the status outputs.

Power on Configuration 
After reset the STAT_MUX_OUT pins are 
inputs which define the power on configuration 
status of the router.  The pin mappings are 
listed in section 5.6. 
These pins should be pulled up or down (e.g. 
4k7 
Ω) to provide the required power on 
configuration input values.  
Normal Operation 
After the power on reset configuration of the 
router has been read from STAT_MUX_OUT 
the pins are driven as outputs by the router. 
The function of these output pins is defined by 
STAT_MUX_ADDR(3:0)
. Further details are 
given in section 6.3.
