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.
