Note 1. The DS shift setting (WRAPCFG.DSSFTCSx[4:0]) is 01000b for xSPI200.

Note 2. Specification at 133 MHz / Specification at 100 MHz

Note 3. These are values when the OEN assertion is extended in the Output Enable Asserting extension bit (COMCFG.OEASTEX = 1).

Note 4. These are the values when the CS assertion is extended in the CS asserting extension bit (LIOCFGCSn.CSASTEX = 1).

Note 5. These are the values when the tCKLDSL constraint is satisfied.

Note 6. This constraint is necessary only to satisfy the tDSLCSH requirement in JESD251, which specifies that tDSLCSH must be at least 80%

of tPERIOD. Set LIOCFGCSn.CSNEGEX to the appropriate value to ensure the memory specification complies with this constraint.

Note 7. e = LIOCFGCSn.CSNEGEX

Note 8. If the DS is high during the command and modifier phase when using JESD251 Profile 2.0 memory, the time from CS low to DS

high must also meet this specification.

Note 9. When using JESD251 Profile 1.0 memory or JESD251 Profile 2.0 memory with LIOCFGCSn.LATEMD set to 0, this constraint does

not apply if the internal pull-down resistor of the DS pin is enabled.
