The maximum operating frequency is given in tables 35-32, 35-33,
Flash access time when the processor is fetching code out of it. The tables 35-32, 35-33,
device maximum operating frequency depending on the field FWS of the MC_FMR register. This field defines the number
of wait states required to access the Embedded Flash Memory.
Table 35-32. Embedded Flash Wait State (VDDCORE set at 1.80V, minimum 1.65V)
Table 35-33. Embedded Flash Wait States (VDDCORE set at 1.75V, minimum 1.70V)
Table 35-34. Embedded Flash Wait States (VDDCORE set at 1.65V, minimum 1.60V)
Table 35-35. Embedded Flash Wait States (VDDCORE set at 1.55V, minimum 1.50V)
