The deep power-down mode is a new feature of the Low-power SDRAM. When this mode is
activated, all internal voltage generators inside the device are stopped and all data is lost.
This mode is activated by setting the low-power command bits [LPCB] to ‘11’. When this mode is
enabled, the DDRSDRC leaves normal mode (mode == 000) and the controller is frozen. To exit
deep power-down mode, the low-power bits (LPCB) must be set to “00”, an initialization
sequence must be generated by software. See
tialization” on page
