• EBI_CS1A: EBI Chip Select 1 Assignment
0 = EBI Chip Select 1 is assigned to the Static Memory Controller.
1 = EBI Chip Select 1 is assigned to the SDRAM Controller.
• EBI_CS3A: EBI Chip Select 3 Assignment
0 = EBI Chip Select 3 is only assigned to the Static Memory Controller and EBI_NCS3 behaves as defined by the SMC.
1 = EBI Chip Select 3 is assigned to the Static Memory Controller and the SmartMedia Logic is activated.
• EBI_CS4A: EBI Chip Select 4 Assignment
0 = EBI Chip Select 4 is only assigned to the Static Memory Controller and EBI_NCS4 behaves as defined by the SMC.
1 = EBI Chip Select 4 is assigned to the Static Memory Controller and the Compact Flash Logic Slot 0 is activated.
• EBI_CS5A: EBI Chip Select 5 Assignment
0 = EBI Chip Select 5 is only assigned to the Static Memory Controller and EBI_NCS5 behaves as defined by the SMC.
1 = EBI Chip Select 5 is assigned to the Static Memory Controller and the Compact Flash Logic Slot 1 is activated.
• EBI_DBPUC: EBI Data Bus Pull-Up Configuration
0 = EBI D0 - D15 Data Bus bits are internally pulled-up to the VDDIOM1 power supply.
1 = EBI D0 - D15 Data Bus bits are not internally pulled-up.
• EBI_DRIVE: EBI I/O Drive Configuration
This allows to avoid overshoots and give the best performances according to the bus load and external memories.
• DDR_DRIVE: DDR2 dedicated port I/O slew rate selection
This allows to avoid overshoots and give the best performances according to the bus load and external memories.
0 = Low Drive, optimized for load capacitance < 30 pF.
