Currently there are EVMs equipped with DDR4, does it enable DDR4 function MPSM (Maximum power savings mode)?

is any SDK support it?

Yes, check the DDRCTL_PWRCTL register, MPSM_EN bit. I don't believe the SDK supports this, but the hardware does.

thank you.

so is that means currently EVK implement it but not use as default, right?

Can you guide me where and how to check the DDRCTL_PWRCTL register, MPSM_EN bit?

Casper, the TRM https://www.ti.com/lit/pdf/spruid7 has a description of the register
