45.10.10 Embedded Flash Characteristics
The maximum operating frequency is given in tables
time when the processor is fetching code out of it. The tables
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
Note: The embedded flash is fully tested during production test, the flash contents is not set to a known state prior to ship-
ment. Therefore, the flash contents should be erased prior to programming an application.
