Link Training Frame Contents for Lane 3 Fields
Bit | Name | Description | Access | Reset |
---|---|---|---|---|
30 | lp_receiver_ready_ln3 | Link Partner Receiver Ready Status for Lane 3 1: The link partner receiver has determined that training is complete and is prepared to receive data 0: The link partner receiver is requesting that training continue |
RO | 0x0 |
29:24 | lp_coefficient_status_ln3 | TX EQ Coefficient Status from Link Partner for Lane 3 [5:4] Status of Link Partner (+1) TX EQ Coefficient [3:2] Status of Link Partner (0) TX EQ Coefficient [1:0] Status of Link Partner (-1) TX EQ Coefficient
The Coefficient values are encoded as follows:
|
RO | 0x0 |
23 | lp_preset_coefficients_ln3 | PRESET Command from Link Partner on Lane 3 1: Set local TX EQ to PRESET 0: Normal Operation This Field is normally Read-only, and the values are normally controlled by the Remote Partner Link Training SM. When ovride_local_coef_enable=1, this field becomes writable, and is used to set the local values. When ovride_local_coef_enable=1, use updated_local_coef_ln3=1 to write the local values. |
RW | 0x0 |
22 | lp_initialize_coefficients_ln3 | INIT Command from Link Partner on Lane 3 1: Set local TX EQ to INIT 0: Normal Operation This Field is normally Read-only, and the values are normally controlled by the Remote Partner Link Training SM. When ovride_local_coef_enable=1, this field becomes writable, and is used to set the local values. When ovride_local_coef_enable=1, use updated_local_coef_ln3=1 to write the local values. |
RW | 0x0 |
21:16 | lp_coefficient_update_ln3 | TX EQ Coefficient Request from Link Partner on Lane 3 [5:4] Control for Local (+1) TX EQ Coefficient [3:2] Control for Local (0) TX EQ Coefficient [1:0] Control for Local (-1) TX EQ Coefficient This Field is normally Read-only, and the values are normally controlled by the Remote Partner Link Training SM. When ovride_local_coef_enable=1, this Field becomes writable, and is used to set the local values. When ovride_local_coef_enable=1, use updated_local_coef_ln3=1 to write the local values.
The Coefficient values are encoded as follows:

RW | 0x0 |
14 | ld_receiver_ready_ln3 | Local Receiver Ready Status for Lane 3 1: The local device receiver has determined that training is complete and is prepared to receive data 0: The local device receiver is requesting that training continue |
RO | 0x0 |
13:8 | ld_coefficient_status_ln3 | Local TX EQ Coefficient Status for Lane 3 [5:4] Status of Local (+1) TX EQ Coefficient [3:2] Status of Local (0) TX EQ Coefficient [1:0] Status of Local (-1) TX EQ Coefficient
The Coefficient values are encoded as follows:
|
RO | 0x0 |
7 | ld_preset_coefficients_ln3 | PRESET Coefficients command to Link Partner on Lane 3 1: PRESET Coefficients 0: Normal Operation This field is normally Read-only, and the values are normally controlled by the Link Training SM. When ovride_lp_coef_enable=1, this field becomes writable, and is used to set the values sent to the Link Partner. When ovride_lp_coef_enable=1, useupdated_lp_coef_ln3=1 to transmit the values to the Link Partner. The PRESET command is defined in IEEE 802.3 CL72.6.10.2.3.1. |
RW | 0x0 |
6 | ld_initialize_coefficients_ln3 | INIT Coefficients command to Link Partner on Lane 3 1: INIT Coefficients 0: Normal Operation This field is normally Read-only, and the values are normally controlled by the Link Training SM. When ovride_lp_coef_enable=1, this field becomes writable, and is used to set the values sent to the Link Partner. When ovride_lp_coef_enable=1, useupdated_lp_coef_ln3=1 to transmit the values to the Link Partner. The INIT command is defined in IEEE 802.3 CL72.6.10.2.3.2. |
RW | 0x0 |
5:0 | ld_coefficient_update_ln3 | TX EQ Coefficient Request to Link Partner on Lane 3 [5:4] Control for Link Partner (+1) TX EQ Coefficient [3:2] Control for Link Partner (0) TX EQ Coefficient [1:0] Control for Link Partner (-1) TX EQ Coefficient This field is normally Read-only, and the values are normally controlled by the Link Training SM. When ovride_lp_coef_enable=1, this field becomes writable, and is used to set the values sent to the Link Partner. When ovride_lp_coef_enable=1, use updated_lp_coef_ln3=1 to transmit the values to the Link Partner.
