Note:
  1. Maximum Flash operating frequencies are given in the table above, but are limited by the Embedded Flash access time when the processor is fetching code out of it. Theses tables provide the device maximum operating frequency defined by the field FWS[3:0] of the EEFC_FMR register. This field defines the number of Wait states required to access the Embedded Flash Memory.
