Bit R/W Name Description
• [4:0]: Selector
• [9:5]: Echoed nonce which are set by the state machine
• [12:10]: Pause bits
• [13]: Remote Fault bit
• [14]: ACK which is controlled by the SM
• [15]: Next page bit
Bit 49, the PRBS bit, is generated by the Auto-Negotiation TX
state machine.
21:16 RW Override AN_
TECH[5:0]
Specifies an AN_TECH value to override. The following
encodings are defined:
• [16]: AN_TECH[0] = 1000Base-KX
• [17]: AN_TECH[1] = XAUI
• [18]: AN_TECH[2] = 10GBASE-KR
• [19]: AN_TECH[3] = 40G
• [20]: AN_TECH[4] = CR-4
• [21]: AN_TECH[5] = 100G
You must write 0xC0[5] to 1'b1 for these overrides to take
effect.
25:24
RW Override AN_
FEC[1:0]
Specifies an AN_FEC value to override. The following
encodings are defined:
• [24]: AN_ FEC [0] = Capability
• [25]: AN_ FEC [1] = Request
You must write 0xC0[5] to 1'b1 for these overrides to take
effect.
30:28 RW Override AN_
PAUSE[2:0]
Specifies an AN_PAUSE value to override. The following
encodings are defined:
• [28]: AN_PAUSE[0] = Pause Ability
• [29]: AN_PAUSE[1] = Asymmetric Direction
• [30]: AN_PAUSE[2] = Reserved
Need to set 0xC0 bit-5 to take effect.
0xC4 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:
• [4:0]: Correspond to bits 20:16 which are TX nonce bits.
• [29:5]: Correspond to page bit 45:21 which are the
technology ability.
Bit 49, the PRBS bit, is generated by the Auto-Negotiation TX
state machine.
