0b = Not 1000BASE-X full-duplex capable.
0b = Not 1000BASE-X half-duplex capable.
1b =1000BASE-T full-duplex capable.
1b =1000BASE-T half-duplex capable.
Reserved, set to 0x000.
1b = Disable link pulse.
0b = Enable link pulse.
Changes to these bits are disruptive to the normal
operation; therefore, any changes to these registers
must be followed by software reset to take effect.
1x, 2x,...8x is the number of times the PHY attempts
to establish GbE link before the PHY downshifts to
the next highest speed.
000b = 1x.
100b = 5x.
001b = 2x.
101b = 6x.
010b = 3x.
110b = 7x.
011b = 4x.
111b = 8x.
Changes to these bits are disruptive to the normal
operation; therefore, any changes to these registers
must be followed by software reset to take effect.
1b = Enable downshift.
0 = Disable downshift.
If link is forced to be good, the link state machine is
bypassed and the link is always up. In 1000BASE-T
mode this has no effect.
1b = Force link good.
0b = Normal operation.
After a hardware reset, both bits take on the value of
pd_config_edet_a.
0xb = Off.
10b = Sense only on Receive (energy detect).
11b = Sense and periodically transmit NLP (energy
detect+TM).
When using a cable exceeding 100 meters, the
10BASE-T receive threshold must be lowered in
order to detect incoming signals.
1b = Lower 10BASE-T receive threshold.
0b = Normal 10BASE-T receive threshold.
