System low power enable
0 The system is prevented from entering low power state.
1 The system will enter low power state when a quiesce request from the PowerPC core arrives. This bit
power, according to SLPEN setting. DDR SDRAM will enter self-refresh mode (if enabled by
DDR_SDRAM_CFG[SREN] memory controller register) and DDR clocks (MCK n ) are shut off. This bit is
cleared when the device exits from low power state. Note that setting this bit without setting SLPEN has
no effect.
