falling edge of EXT_TICK_OUT. The

EXT_TIME_OUT(7:0)

value is held until the next

time-code is output.

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

5.5 STATUS INTERFACE SIGNALS

The status interface signals are listed in Table 5-5.

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.
