10.3.4 Powering off SRAM blocks

Table 10.3. EMU Wakeup Triggers from Low Energy Modes

The SRAM blocks can be individually disabled using the POWERDOWN bitfield in the EMU_MEMCTRL
register. To disable a block means that the power source is removed from the entire block, which will
conserve energy. Once a block has been disabled it can only be enabled by reset.
All the blocks can be turned off except the first one.
