To activate this mode, the command must be followed by a write to the DDR-SDRAM. 2 (PRCGALL_CMD): The MPDDRC issues an “All Banks Precharge” command when the DDR-SDRAM device is accessed regardless of the cycle. To activate this mode, the command must be followed by a write to the SDRAM. 3 (LMR_CMD): The MPDDRC issues a “Load Mode Register” command when the DDR-SDRAM device is accessed regardless of the cycle. To activate this mode, the command must be followed by a write to the DDR-SDRAM. 4 (RFSH_CMD): The MPDDRC issues an “Auto-Refresh” Command when the DDR-SDRAM device is accessed regardless of the cycle. Previously, an “All Banks Precharge” command must be issued. To activate this mode, the command must be followed by a write to the DDR-SDRAM. 5 (EXT_LMR_CMD): The MPDDRC issues an “Extended Load Mode Register” command when the SDRAM device is accessed regardless of the cycle. To activate this mode, the command must be followed by a write to the DDR-SDRAM. The write in the DDR-SDRAM must be done in the appropriate bank. 6 (DEEP_CMD): Deep power mode: Access to deep power-down mode 7 (LPDDR2_CMD): The MPDDRC issues an “LPDDR2 Mode Register” command when the Low-power DDR2-SDRAM device is accessed regardless of the cycle.
