• MODE: DDRSDRC Command Mode
This field defines the command issued by the DDRSDRC when the SDRAM device is accessed. This register is used to ini-
tialize the SDRAM device and to activate deep power-down mode.

DDRSDRC Mode Register
Description
Normal Mode. Any access to the DDRSDRC will be decoded normally. To activate this mode, command must be followed
by a write to the SDRAM.
The DDRSDRC issues a NOP command when the SDRAM device is accessed regardless of the cycle. To activate this
mode, command must be followed by a write to the SDRAM.
The DDRSDRC issues an “All Banks Precharge” command when the SDRAM device is accessed regardless of the cycle.
To activate this mode, command must be followed by a write to the SDRAM.
The DDRSDRC issues a “Load Mode Register” command when the SDRAM device is accessed regardless of the cycle.
To activate this mode, command must be followed by a write to the SDRAM.
The DDRSDRC issues an “Auto-Refresh” Command when the SDRAM device is accessed regardless of the cycle.
Previously, an “All Banks Precharge” command must be issued. To activate this mode, command must be followed by a
write to the SDRAM.
The DDRSDRC issues an “Extended Load Mode Register” command when the SDRAM device is accessed regardless of
the cycle. To activate this mode, the “Extended Load Mode Register” command must be followed by a write to the SDRAM.
The write in the SDRAM must be done in the appropriate bank.
Deep power mode: Access to deep power-down mode
