7.10.5.14.1.2 OSPI0 Without Data Training

Note

Timing parameters defined in this section are only applicable when data training is not implemented

and DLL delays are configured as described in Table 7-97 and Table 7-100.

7.10.5.14.1.2.1 OSPI0 PHY SDR Timing

Table 7-97 defines DLL delays required for OSPI0 PHY SDR Mode. Table 7-98, Figure 7-82, Figure 7-83, Table

7-99, and Figure 7-84 present timing requirements and switching characteristics for OSPI0 PHY SDR Mode.
