DESCRIPTION
PLLREADY
0 = PLL is not locked
1 = PLL is locked
POLARITY_INV_3
This bit indicates reverse polarity on channel 3 when operating in
1000BASE-T mode.
0 = Channel 3 polarity is correct
1 = Channel 3 polarity is reversed
POLARITY_INV_2
This bit indicates reverse polarity on channel 2 when operating in
1000BASE-T mode.
0 = Channel 2 polarity is correct
1 = Channel 2 polarity is reversed
POLARITY_INV_1
This bit indicates reverse polarity on channel 1 when operating in
1000BASE-T mode.
0 = Channel 1 polarity is correct
1 = Channel 1 polarity is reversed
POLARITY_INV_0
This bit indicates reverse polarity on channel 0 when operating in
1000BASE-T mode.
0 = Channel 0 polarity is correct
1 = Channel 0 polarity is reversed
RESERVED
CLKREF_SEL
0 = Reference clock frequency = 125MHz
1 = Reference clock frequency = 25MHz
The value of this bit is based upon the configuration strap settings, as
detailed in Section 3.8.1.1, "Configuration Straps," on page 29.
