Power Management

The SDRAMC may be clocked through the Power Management Controller (PMC), thus the programmer must first configure the PMC to enable the SDRAMC clock.

The SDRAM clock on pin SDCK is output as soon as the first access to the SDRAM is made during the initialization phase. To stop the SDRAM clock signal, the SDRAMC_LPR must be programmed with the self-refresh command.
