Force FX Signal Detect
Forces the DM9301FP FX interface Signal Detect true
Initiated at an H/W reset. Active high.
Test Port Enable:
Enables the DM9301FP Test Port features.
Initiated at an H/W reset. Active high.
Test Port Mux:
Controls the DM9301FP 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 an H/W reset. Active high.
Bypass Scrambler:
Controls the DM9301FP 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 an H/W reset. Active high.
Power and Ground Pins :
The power (VCC) and ground (GND) pins of the DM9301FP are grouped in pairs of two categories - Digital
Circuitry Power/Ground Pairs and Analog Circuitry Power/Ground Pair.
