DP83867CR: 1000 Base Test Mode 1. "Reg 0x01D5 = 0xF508"

F.N

Part Number: DP83867CR

Hi team,

When my customer conducted the compliance test it failed with the 1000 Base Test Mode 1.
Then the customer passed the test after setting "Reg 0x01D5 = 0xF508" according to the
description of the following Application Report: www.ti.com/.../snla239a.pdf

The customer wants to know what it is setting for.
I can't find the description of the Reg 0x01D5 on the datasheet.
So, Please let me know it.

Best regards,
Fumio Nakano

Hi Nakano-san,

0x1D5 is internal register setting required for outputting the correct waveform for compliance testing. The register is related to internal operation of the PHY so we cannot disclose the information.

Kind regards,
Ross
