Bit R/W Name Description
0x4
C3
15:0
RW User base page low The AN TX state machine uses these bits if the AN base
pages ctrl bit is set. The following bits are defined:
• [15]: Next page bit
• [14]: ACK, controlled by the SM
• [13]: Remote Fault bit
• [12:10]: Pause bits
• [9:5]: Echoed nonce, set by the state machine
• [4:0]: Selector
The auto generation TX state machine generates the
PRBS bit 49.
21:16
RW Override AN_
TECH[5:0]
AN_TECH value to override. The following bits are defined:
• Bit-16 = AN_TECH[0]= 1000BASE-KX
• Bit-18 = AN_TECH[2] = 10GBASE-KR
You must set 0xC0 bit-5 for this to take effect .
25:24 RW Override AN_
FEC[1:0]
AN_FEC value to override. The following bits are defined:
• Bit-24 = AN_FEC [0] = Capability
• Bit-25 = AN_FEC [1] = Request
You must set 0xC0 bit-5 for this to take effect.
30:28 RW Override AN_
PAUSE[2:0]
AN_PAUSE value to override. 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 0xC0 bit-5 for this to take effect.
0x4
C4
31:0 RW User base page high The AN TX state machine uses these bits if the AN base
pages ctrl bit is set. The following bits are defined:
• [29:5]: Correspond to page bits 45:21, the technology
ability.
• [4:0]: Correspond to bits 20:16, the TX nonce bits.
The AN TX state machine generates the PRBS bit 49.
