Word Addr Bit R/W Name Description
0x4C3
15:0
RW User base page low The Auto Negotiation TX state machine uses these
bits if the Auto Negotiation base pages ctrl bit is
set. The following bits are defined:
• [15]: Next page bit
• [14]: ACK which is controlled by the SM
• [13]: Remote Fault bit
• [12:10]: Pause bits
• [9:5]: Echoed nonce which are set by the state
machine
• [4:0]: Selector
Bit 49, the PRBS bit, is generated by the Auto
Negotiation TX state machine.

RW Override AN_
TECH[5:0]
AN_TECH value with which to override the current
value. The following bits are defined:
• Bit-16 = AN_TECH[0]= 1000BASE-KX
• Bit-17 = AN_TECH[1] = XAUI
• Bit-18 = AN_TECH[2] = 10GBASE-KR
• Bit-19 = AN_TECH[3] = 40G
• Bit-20 = AN_TECH[4] = CR-4
• Bit-21 = AN_TECH[5] = 100G
You must set 0x4C0 bit-5 for this to take effect .
25:24 RW Override AN_
FEC[1:0]
AN_FEC value with which to override the current
value. The following bits are defined:
• Bit-24 = AN_ FEC [0] = Capability
• Bit-25 = AN_ FEC [1] = Request
You must set 0x4C0 bit-5 for this to take effect.
30:28 RW Override AN_
PAUSE[2:0]
AN_PAUSE value with which to override the
current value. The following bits are defined:
• Bit-28 = AN_PAUSE [0] = Pause Ability
• Bit-29 = AN_PAUSE [1] = Asymmetric
Direction
• Bit-30 = AN_PAUSE [2] = Reserved
You must set 0x4C0 bit-5 for this to take effect.
0x4C4 31:0 RW User base page high The Auto Negotiation TX state machine uses these
bits if the Auto Negotiation base pages ctrl bit is
set. The following bits are defined:
• [29:5]: Correspond to page bits 45:21 which are
the technology ability.
• [4:0]: Correspond to bits 20:16 which are TX
nonce bits.
Bit 49, the PRBS bit, is generated by the Auto
Negotiation TX state machine.
