DP83867CR: About DP83867CR with 10 / 100BASE configuration

Hello.
This is a question when making a 10 / 100BASE only system with DP83867.

If I make a 1000BASE system, I understand that four pairs of TD_P / N_A, TD_P / N_B, TD_P / N_C, and TD_P / N_D signals are connected to the connector via a transformer.

In a 10 / 100BASE only system, two pairs of TX and RX signals are used. At that time, only TD_P / N_A and TD_P / N_B are used, and TD_P / N_A is connected as a TX pair via a transformer. , TD_P / N_B is connected to the connector as RX pair.
(TD_P_A is 1pin, TD_N_A is 2pin, TD_P_B is 3pin, TD_N_B is 6pin)

Will it be established with such a connection?

I understand that it is reasonable to use a PHY device that supports only 10 / 100BASE.
However, the client specifies that the PHY uses DP83867.

Regards.
