2.12.1.3. Auto Negotiation Config Register 1
Offset: 0xC0
Auto Negotiation Config Register 1 Fields
Bit | Name | Description | Access | Reset |
---|---|---|---|---|
31:16 | consortium_oui | Consortium Organizationally Unique Identifier (OUI) (lower 16 bits) Sets the lower bits of the OUI (as defined in IEEE 802.3 Annex 73A) used in sending and receiving Next Pages. |
RW | 0x737D |
11 | ignore_consortium_next_page_tech_ability_code | Ignore Consortium NextPage Tech Ability Code 1: AN function accepts any unformatted Next Page after a formatted Next Page tagged with the proper OUI for resolving Consortium AN modes 0: The AN function only accepts an unformatted Next Page with the code 0x003 in bits D8:D0 |
RW | 0x0 |
10 | enable_consortium_next_page_override | Enable Consortium Next Page override 1: Data sent to the consortium Next Page comes from the Consortium Next Page Override Register (0xCD) instead of being set automatically 0: Data is filled based on supported IP modes |
RW | 0x0 |
9 | enable_consortium_next_page_receive | Enable Consortium Next Page receive 1: Enable decoding received Consortium Next Pages for purpose of resolving AN 0: The AN function ignores the received next pages |
RW | 0x1 |
8 | enable_consortium_next_page_send | Enable Consortium Next Page send Send Consortium-standard next pages immediately after the base page. If User next pages are enabled, consortium pages is sent after the last user next page. |
RW | 0x0 |
7 | ignore_nonce_field | Ignore Nonce Field 1: Ignore the Nonce field during AN 0: Normal operation
The default value for this bit in synthesis is 0 and in simulation is 1. |
RW | 0x0 |
6 | override_an_chan_enable | Override AN Master Channel (as set by AN_CHAN) 1: Use AN Master channel selection from 0xCC[1:0] 0: Use AN Master channel specified via generation parameter |
RW | 0x0 |
5 | override_an_parameters_enable | Override AN Parameters 1: Use the bits from parameter override CSRs to compose the default base page 0: Normal operation |
RW | 0x0 |
3 | local_device_remote_fault | Force Local device remote fault 1: Signal a remote fault using appropriate bit in the AN pages 0: Normal operation |
RW | 0x0 |
2 | an_next_pages_ctrl | Enable User Controlled AN Next Pages 1: User-controlled next pages are enabled. You can send any arbitrary data via the User next page high/low bits (0xC6[31:0]/0xC5[15:0]). The IP pauses on each next page transaction until you set 0xC1[8]. 0: User-controlled next page control is disabled. The IP generates the null message to send as next pages, and does not pause on next page transactions. Set this bit before AN begins, and clear this bit once your next page activity completes to allow AN to finish. |
RW | 0x0 |
1 | an_base_pages_ctrl | Enable User Controlled AN Base Pages To ensure proper HCD resolution when changing the Tech Ability and FEC fields, set the equivalent bits in the parameter override CSR through override_an_parameters_enable bit. 1: User controlled base pages are enabled; the User Base page CSRs control the base page used for AN 0: The AN logic will automatically generate base pages based on the Ethernet Core Variant and its parameters
|
RW | 0x0 |
0 | enable_an | Enable AutoNegotiation 1: Enable AutoNegotiation (default) 0: Disable AutoNegotiation
|
RW | 0x1 |
