Deep power-down mode
This mode is selected by writing the value three to the LPR.LPCB field. When this mode is acti-
vated, all internal voltage generators inside the SDRAM are stopped and all data is lost.
When this mode is enabled, the user must not access to the SDRAM until a new initialization
sequence is done (See
