I want to confirm the specification of SDCLK for i.MX6Dual.
It is described at P5 in IMX6DQAEC Rev4 as following.
External memory interfaces:
16-bit, 32-bit, and 64-bit DDR3-1066
I understand that it supports up to 533MHz as SDCLK.
I cannot find the minimum value for the SDCLK.
What is the minimum value for SDCLK?
Is it able to use DDR3-800(SDCLK=400MHz)?
