Force FX Signal Detect
Forces the DM9301 FX interface Signal Detect true
Initiated at a H/W reset. Active high.
Test Port Enable:
Enables the DM9301 Test Port features.
Initiated at a H/W reset. Active high.
Test Port Mux:
Controls the DM9301 Test Port Input and Output bits.
A value of zero indicates the TX interface and a value of
one indicates the FX interface. TPEN must be true (one)
for this signal to take effect.
Initiated at a H/W reset. Active high.
Bypass Scrambler:
Controls the DM9301 TX interface Scrambler/De-
scrambler function. A value of zero indicates to
scramble and de-scramble the TX interface 5-bit
symbol data to and from the FX interface. A value of one
bypasses the scrambler/de-scrambler function.
Initiated at a H/W reset. Active high.
