DP83TD510E: Strap configuration for GPIO2

Oba

Part Number: DP83TD510E

Hello,

As far as I read the datasheet, GPIO2 has to be externally pulled up or pulled down.
But Table 5-1 in the datasheet says GPIO2 has internal pull down like other strap pins.
Why does only this GPIO2 pin absolutely require external pull up/down?

Oba

Hi Oba,

The GPIO_2 pin requires an external strap resistor. The table 5-2 in the datasheet looks to be incorrectly formatted.

Hello Justin,

I have an additional question.
So GPIO_2 doesn't have neither internal pull-up and pull down and 2.49K ohm is recommended for both external pull-up and down.
Correct?

Oba
