• CAS: CAS Latency
The reset value is 2 cycles.
• DLL: Reset DLL
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.
• DIC/DS: Output Driver Impedance Control
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: This field is found only in DDR2-SDRAM devices.
• DIS_DLL: Disable DLL
Reset value is 0.
0 = Enable DLL
1 = Disable DLL
Note: This field is found only in DDR2-SDRAM devices.
• OCD: Off-chip Driver
Reset value is 7.
Note: OCD is NOT supported by the controller, but these values MUST be programmed during the initialization sequence.
