7.10.5.17.1.2 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 7-114 and Table 7-117.

7.10.5.17.1.2.1 OSPI0 PHY SDR Timing

Table 7-114 defines DLL delays required for OSPI0 PHY SDR Mode. Table 7-115, Figure 7-98, Figure 7-99,

Table 7-116, and Figure 7-100 present timing requirements and switching characteristics for OSPI0 PHY SDR

Mode.
