C5
15:0 RW User Next page low The AN TX state machine uses these bits if the AN next
pages ctrl bit is set. The following bits are defined:
• [15]: Next page bit
• [14]: ACK, controlled by the state machine
• [13]: Message Page (MP) bit
• [12]: ACK2 bit
• [11]: Toggle bit
For more information, refer to Clause 73.7.7.1 Next Page
encodings of IEEE 802.3ap-2007. Bit 49, the PRBS bit, is
generated by the AN TX state machine.
0x4
C6
31:0 RW User Next page high The AN TX state machine uses these bits if the AN next
pages ctrl bit is set. Bits [31:0] correspond to page bits
[47:16]. Bit 49, the PRBS bit, is generated by the AN TX
state machine.

C7
15:0 RO LP base page low The AN RX state machine receives these bits from the
link partner. The following bits are defined:
• [15] Next page bit
• [14] ACK, which is controlled by the state machine
• [13] RF bit
• [12:10] Pause bits
• [9:5] Echoed nonce which are set by the state machine
• [4:0] Selector
