33.6.5.3 Deep Powerdown Mode

This mode is selected by configuring SDRAMC_LPR.LPCB to 3. When this mode is activated, all internal voltage generators inside the SDRAM are stopped and all data is lost.

When this mode is enabled, the application must not access the SDRAM until a new initialization sequence is done (see “SDRAM Device Initialization”).

See the following figure.
