DP83869HM: MDI_CROSSOVER_MODE

Ross Petty
Intellectual 300 points
Part Number: DP83869HM

Tool/software:

The register description for the MDI_CROSSOVER_MODE field of the PHY_CONTROL register (reg 0x10) says it's a 2 bit value, but the description lists 4 bit numbers (ex: Ah = Enable Automatic Crossover). 

Clearly I cannot write a hex A to a 2 bit field, so what is the correct description?

    Hi Ross,

    I see how this description is confusing. I believe the intent here was for Ah = ten (10) and Bh = eleven (11). Your concern is correct and I have noted this down for future data sheet revisions. The correct description should be 0h, 1h, 2h, and 3h. Please confirm if this works for you.

    Regards,

    Alvaro
