The EMIF can gate EMIF_FICLK. There is an internal mechanism that can stop EMIF_FICLK automatically. EMIF_FICLK is stopped only after the SDRAM is put into self-refresh mode and the power-idle protocol on the local bus completes. The EMIF_FICLK frequency can be changed only after putting the external SDRAM in self-refresh mode.
The EMIF waits for the DLL lock before performing any memory access.
EMIF_FICLK frequency is equal to half of the EMIF_PHY_FCLK frequency.
