1b = Link partner 1000BASE-T half-duplex capable.
0b = Link partner not 1000BASE-T half-duplex capable.
Note: Logically, bits 11:10 might be regarded as an
extension of the Technology Ability field in register 5.
Reserved
These bits contain a cumulative count of the errors
detected when the receiver is receiving idles and both
local and remote receiver status are operating correctly.
The count is held at 255 in the event of overflow and is
reset to zero by reading register 10 via the
management interface or by reset.
MSB of idle error count.
Reserved
0b = Not 1000BASE-X full-duplex capable.
1b = Resolves MDI/MDI-X configuration before forcing
speed.
0b = Does not resolve MDI/MDI-X configuration before
forcing speed.
Count symbol errors (bit 13) and count false carrier
events (bit 14) control the type of errors that the Rx
error counter (register 20, bits 15:0) counts (refer to
Table
1b = Rx error counter counts false carrier events.
0b = Rx error counter does not count false carrier
events.
Count symbol errors (bit 13) and count false carrier
events (bit 14) control the type of errors that the Rx
error counter (register 20, bits 15:0) counts (refer to
Table
1b = Rx error counter counts symbol errors.
0b = Rx error counter counts CRC errors.
Reserved.
1b = Enables automatic MDI/MDI-X configuration.
0b = Disables automatic MDI/MDI-X configuration.
1b = Manual MDI-X configuration.
0b = Manual MDI configuration.
23). The default is to count CRC errors.
