Hi all

 

I want to know the time until DRAM_RESET goes high and CKE goes high.

I'm using i.MX6UL and DDR3.

 

Q1.

User can change the value to set by [5: 0] RST_to_CKE of MMDC_MDOR register.

Am I correct ?

 

 

Q2.

I set the value to 0x23 but the measured value is 424ns.

I understand that the time change by the parameter but I can't understand how to calculate.

Could you tell me how to calculate ?

 

 

I referred the following thread.

So if I need make case, please tell me.
