In the user manual (UM10912) it states that the external memory controller (EMC) can put the connected device into low power mode. See remark at the bottom of the attached page. I am able to set the CE and CS bits using the fsl_emc driver included in the SDK, but where is the DP bit and how does one set it?
I have tried the following functions prior to putting the LPC device to sleep, but results in terms of current consumption are not consistent.
I am using Micron SDRAM. According to their datasheet, power-down requires a CKE high to low transition while all banks are idle. Do I need to ensure that all banks are idle before the above commands? If so, what is the best way to achieve that?
