Pull-up resistor value on SDIO line of AM1808

Hi,

AM1808's EVM shows that SDIO has a internal pull resistor.

I didn't  find out this thing in data sheet of AM1808. It also not shown pull up resistor's value.

Some TI processor shows it is 51K value and some shows 4.7K .

Can any one tell AM1808's SDIO line required external pull up or not ?

If required then how much  resister value required ? If any calculation available then please share.

 

Thanks

Hitesh
