52 / 149 page  Document Number: 001-98283 Rev. *M Page 51 of 148 S25FL128S/S25FL256S Read DDR Data Learning Pattern (DLP) bits may be placed within the dummy cycles immediately before the start of read data, if there are 5 or more dummy cycles. See Section 9.4 Read Memory Array Commands on page 84 for more information on the DLP. Note: 1. When using DDR I/O commands with the Data Learning Pattern (DLP) enabled, a Latency Code that provides 5 or more dummy cycles should be selected to allow 1 cycle of additional time for the host to stop driving before the memory starts driving the 4 cycle DLP. It is recommended to use LC 10 for DDR Fast Read, LC 01 for DDR Dual IO Read, and LC 00 for DDR Quad IO Read, if the Data Learning Pattern (DLP) for DDR is used. Table 26.
