POWERDOWN
Individual 4KB RAM block power-down. When a block is powered down, it cannot be powered up again. The block will be powered
up after the reset. Block 0 (address range 0x20000000-0x20000FFF) may never be powered down.
Reserved
LOCKKEY
Write any other value than the unlock code to lock all EMU registers from editing. Write the unlock code to unlock. When reading
the register, bit 0 is set when the lock is enabled.
