DP83867IR: Strap Configuration

Tool/software:

Hi Team,

I would like some advice on strap configuration.
I understand that there are pins for strap configuration that are "0=Disable, 1=Enable" and the opposite, "0=Enable, 1=Disable".
We need to avoid incorrect settings.
Is my understanding as attached correct?

The red group is "0=Disable, 1=Enable"
The blue group is "0=Enable, 1=Disable"

If it is clearly stated in the data sheet, please tell me where it is written.

Best Regards,

    Hi Atsushi, 

    I believe your understanding is correct except the Speed Optimization enable function under RX_D7, which should be 0 = Disable, 1 = Enable.

    I think Table 7-5 explains the straps more clearly. Through this table, customer can easily see all the different strap options, and the corresponding 4-level strap configuration, making it easier to choose the correct strap level for each pin. 

    Regards,
