Hi all

 

 

How to decide a tRPA parameter in script aid ?

 

I'm setting a i.MX6SL's DDR3 parameters and using following script aid.

i.MX6SL DDR3 Register Programming Aid

 

I can't find any description and data about tRPA in DDR3's datasheet and find only following description in i.MX6SL's reference manual.

But I can't understand which setting is suit for DDR3.

 

I also checked a DDR3 SDRAM Specification JESD79-3E (July 2010) but can't find any description about it.

 

I attached a DDR3's datasheet.

So could you point where it is in attached datasheet ?
