Power dissipation from the EMIF memory controller can be managed by following methods:
Gating input clocks off to the EMIF memory controller achieves higher power savings when compared to the power savings of self-refresh or power down mode. The input clock to EMIF can be turned off through the use of the Global Clock Module (GCM). Before gating clocks off, the EMIF memory controller must place the SDR SDRAM memory in self-refresh mode. If the external memory requires a continuous clock, the VCLK3 clock domain must not be turned off because this can result in data corruption. See the following subsections for the proper procedures to follow when stopping EMIF memory controller clocks.
