0 = remote receiver status not OK
11 LINK_PARTNER_1000BASE-
T_FULL_DUPLEX_CAPABLE
RO* 0 1 = link partner is 1000BASE-T full duplex capable
0 = link partner is not 1000BASE-T full duplex
capable
10 LINK_PARTNER_1000BASE_T
_HALF_DUPLEX_CAPABLE
RO* 0 1 = link partner is 1000BASE-T half duplex capable
0 = link partner is not 1000BASE-T half duplex
capable
9:8 RESERVED RO 00h ignore on read
7:0 IDLE_ERROR_COUNT RO
CR
00h Number of idle errors since last read
(#)=not LH & *=RW when “writeable link partner ability test mode” (reg 1Fh bit 10) is set
Bit Name RW Default Description
15:3 RESERVED RO 000h Ignore on Read
2 ENABLE LRE REGISTER
ACCESS OVERRIDE
RW 0 1 = Allow access to BroadReach LRE Registers
0 = BroadReach LRE Registers enabled only by
normal operation
1 LRE REGISTER OVERRIDE
VALUE
RW 0 1 = Force Access to IEEE Registers (only available
when 0E.2 = 1)
0 = Force Access to BroadReach LRE Registers
(only available when 0E.2 = 1)
0 LRE REGISTER ACCESS
STATUS
RO 0 1 = BroadReach LRE Registers are currently
accessible
0 = IEEE Registers are currently accessible
Bit Name RW Default Description
15 1000BASE_X_FULL_DUPLEX_
CAPABLE
RO L 0 1 = 1000BASE-X full duplex capable
0 = not 1000BASE-X full duplex capable
