About MMDC1_MDCFG0 "tXP" bit in i.MX6DQ.

[keitanagashima]

Dear All,

Hello.

I have a question about setting the tXP bit.

tXP bit value must set more than 1 clock than tCKE from DDR3 SDRAM Specification JESD79-3E.

If "tXP bit value" > "tCKE bit value", does it work according to the setting?

Or, is it automatically calibrated?

Best Regards,

Keita
