38.8.5 Embedded Flash Characteristics
The maximum operating frequency is given in Table 38-25 but is limited by the Embedded Flash access time when the processor
is fetching code out of it. Table 38-25 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.
Table 38-25. Embedded Flash Wait States
FWS Read Operations Maximum Operating Frequency (MHz)
0 1 cycle 30
1 2 cycles 55
2 3 cycles 55
3 4 cycles 55
