Deep Power-down Mode
This mode is selected by programming the LPCB field to 3 in the SDRAMC Low Power Register.
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 to the SDRAM until a new initializa-
tion sequence is done (See
