Embedded Flash Characteristics
Table 97. DC Flash Characteristics
The maximum operating frequency is given in Table 97 but is limited by the Embedded Flash access time when the proces-
sor is fetching code out of it. Table 98 gives the 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.
