TJA1120A 1000BASET1 to 100BASET1 conversion in Product Datasheet

I have TJA1120A Product Datasheet with me. Section 7.2.1.10 BASE_T1_PMA_CONTROL register has 3:0 MODE for selecting between 1000BASET1 and 100BASET1. Its a MMD1 Register.
Can someone help me out how to utilize this register to make TJA1120A into 100BASET1(at least temporarily its volatile)

Hello @vikyhre ,

It appears there's a typo in the Data Sheet - the Access for BASE_T1_PMA_CONTROL.MODE shall be R - read only. TJA1120 supports only 1000BASE-T1.

Best regards,

Pavel
