86 / 107 page  Data Sheet ADIN1110 REGISTERS analog.com Rev. B | 86 of 107 This address corresponds to the BASE-T1 autonegotiation next page transmit register, Bits[15:0], specified in Clause 45.2.7.23 of Standard 802.3. On power-up or autonegotiation reset, this register contains the default value, which represents a message page with the message code set to null. Write AN_NEXT_PAGE_M and AN_NEXT_PAGE_H before AN_NEXT_PAGE_L. Table 157. Bit Descriptions for AN_NEXT_PAGE_L Bits Bit Name Description Reset Access 15 AN_NP_NEXT_PAGE_REQ Next Page Request. This bit indicates to the link partner that the PHY wants to send a next page. See IEEE Standard 802.3 Subclause 98.2.1.2.9. 0x0 R/W 14 AN_NP_ACK Next Page Acknowledge. See IEEE Standard 802.3 Subclause 98.2.1.2.8. 0x0 R 13 AN_NP_MESSAGE_PAGE Next Page Encoding. Indicates encoding of next page, as follows: 0x1 R/W 0: unformatted next page. 1: message next page. 12 AN_NP_ACK2 Acknowledge 2. Indicates whether the PHY can comply with the message. See IEEE Standard 802.3 Subclause 28.2.3.4.6. 0x0 R/W 11 AN_NP_TOGGLE Toggle Bit. The Toggle bit is used to synchronize pages between the PHYS. This is always read as 0 (the toggle bit is set automatically by the arbitration state machine). 0x0 R [10:0] AN_NP_MESSAGE_CODE Message/unformatted Code Field. For a message page (AN_NP_MESSAGE_PAGE = 1), the valid values are defined in IEEE Standard 802.3. 0x1 R/W 1: null message. 5: organizationally unique identifier tagged message. 6: autonegotiation device identifier tag code. BASE-T1 Autonegotiation Next Page Transmit Register, Bits[31:16] Device Address: 0x07; Register Address: 0x0209, Reset: 0x0000, Name: AN_NEXT_PAGE_M This address corresponds to the BASE-T1 autonegotiation next page transmit register, Bits[31:16], specified in Clause 45.2.7.23 of Standard 802.3. On power-up or autonegotiation reset, this register contains the default value, which represents a message page with the message code set to null. Write AN_NEXT_PAGE_M and AN_NEXT_PAGE_H before AN_NEXT_PAGE_L. Table 158. Bit Descriptions for AN_NEXT_PAGE_M Bits Bit Name Description Reset Access [15:0] AN_NP_UNFORMATTED1 Unformatted Code Field 1. 0x0 R/W BASE-T1 Autonegotiation Next Page Transmit Register, Bits[47:32] Device Address: 0x07; Register Address: 0x020A, Reset: 0x0000, Name: AN_NEXT_PAGE_H This address corresponds to the BASE-T1 autonegotiation next page transmit register, Bits[47:42], specified in Clause 45.2.7.23 of Standard 802.3. On power-up or autonegotiation reset, this register contains the default value, which represents a message page with the message code set to null. Write AN_NEXT_PAGE_M and AN_NEXT_PAGE_H before AN_NEXT_PAGE_L. Table 159. Bit Descriptions for AN_NEXT_PAGE_H Bits Bit Name Description Reset Access [15:0] AN_NP_UNFORMATTED2 Unformatted Code Field 2. 0x0 R/W BASE-T1 Autonegotiation Link Partner Next Page Ability Register, Bits[15:0] Device Address: 0x07; Register Address: 0x020B, Reset: 0x0000, Name: AN_LP_NEXT_PAGE_L This address corresponds to the BASE-T1 autonegotiation link partner's next page ability register, Bits[15:0], specified in Clause 45.2.7.24 of Standard 802.3. The values of AN_LP_NEXT_PAGE_M and AN_LP_NEXT_PAGE_H are latched when this register is read. |
