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 RWS field of the NVMCTRL CTRLA register. This field defines the number of Wait states required to access the Embedded Flash Memory.
  2. For this Flash technology, a maximum number of 8 consecutive writes is allowed per row. Once this number is reached, a row erase is mandatory.
