Reset value is 0.

This field defines the value of Reset DLL.

0 = Disable DLL reset.

1 = Enable DLL reset.

This value is used during the power-up sequence.

Note: This field is found only in DDR2-SDRAM devices.

Reset value is 0.

This field defines the output drive strength.

0 = Normal driver strength.

1 = Weak driver strength.

This value is used during the power-up sequence. This parameter is found in the datasheet as DIC or DS.
Note:

Note: This field is found only in DDR2-SDRAM devices.

Reset value is 0.

0 = Enable DLL

1 = Disable DLL
Note:

Note: This field is found only in DDR2-SDRAM devices.

Reset value is 7.
Notes: 1. OCD is NOT supported by the controller, but these values MUST be programmed during the initialization sequence.

2. This field is found only in DDR2-SDRAM devices.

The DDR controller embedded in the EBI is used at the same time as another memory controller (SMC,..)

Reset value is 0.

0 = Only the DDR controller function is used.

1 = The DDR controller shares the EBI with another memory controller (SMC, NAND,..)
