1000BASE-X AUTO-NEGOTIATION DEBUG (PHY_ADDR = 0X1, REG_ADDR = 1CH, SHADOW
11010B)
Write Enable
During a write to this register, setting LED 1000BASE-X Auto-negotiation Debug register bit 15 to a 1 allows writing to bits
[7:0] of this register. For reading the values of bits [9:0], perform an MDIO write with bit 15 set to a 0 and preferred shadow
values in bits [14:10]. The next MDIO read of register address 1Ch contains the preferred shadow register values in bits [9:0].
Shadow Register Selector
Bits [14:10] of this register must be set to 11010 to enable read/write to the 1000BASE-X Auto-negotiation Debug register.
Consistency Mismatch
Bit 9 of 1000BASE-X Auto-negotiation Debug register indicates a consistency mismatch occurred since last read.
RUDI Invalid
Bit 8 of 1000BASE-X Auto-negotiation Debug register indicates a RUDI (Rx_UnitData Indicate, specified in IEEE 36.2.5.1.6)
invalid detected since last read.
