1000BASE-T:
00b = ± 16 bits.
01b = ± 24 bits.
10b = ± 32 bits.
11b = ± 40 bits.
Reserved, set to 0x00.
Changes to this bit are disruptive to the normal
operation; therefore, any changes to these registers
must be followed by a software reset to take effect.
After a hardware reset, this bit takes on the value of
pd_pwrdn_clk125_a. When pd_pwrdn_clk125_a
transitions from one to zero this bit is set to 0b. When
pd_pwrdn_clk125_a transitions from zero to one this
bit is set to 1b.
1b = fi_125_clk low.
0b = fi_125_clk toggle
After a hardware reset, this bit takes on the value of
pd_pwrdn_clk50_a. When pd_pwrdn_clk50_a
transitions from one to zero this bit is set to 0b. When
pd_pwrdn_clk50_a transitions from zero to one this
bit is set to 1b.
1b = fi_50_clk low.
0b = fi_50_clk toggle.
Reserved, write as 0x1.
Reserved, write as 0x00.
Changes to this bit are disruptive to the normal
operation; therefore, any changes to these registers
must be followed by a software reset to take effect.
This bit determines whether the GMII RX_CLK powers
down when register 0.11, 16_0.2 are used to power
down the 82574 or when the PHY enters the energy
detect state.
1b = Always power up.
0b = Can power down.
Reserved, write as 0x00.
Used to optimize PHY performance in
1000Base-T mode. Set to 0x0003 when
initializing the 82574 to improve BER
performance.
Used to optimize PHY performance in
1000Base-T mode. Set to 0x0000 when
initializing the 82574 to improve BER
performance.
