DP83869EVM: What is 0x01D5 address for?

Part Number: DP83869EVM
Other Parts Discussed in Thread: DP83869HM

Hi team,

I do 1000Base-T compliance test using DP83869EVM.

TI's Ethernet manual describes to write the following picture when testing 1000Base-T Test Mode 1.

What is 0x01D5 address for?

If nothing was written to this address, the output voltage was reduced (705mV ==> 575mV).

Also, the datasheet for the DP83869HM Ethernet PYH IC was not wirtten anything about 0x01D5.

Best regards,

Taka
