The number of program/erase cycles for the EEPROM/D-Flash depends upon the partitioning of D-Flash
used for EEPROM Emulation. Defining RAM size allocated for EEE as EEE-RAM and D-Flash partition
allocated to EEE as EEE_NVM, the minimum number of program/erase cycles is specified depending
upon the ratio of EEE_NVM/EEE_RAM. The minimum ratio EEE_NVM/EEE_RAM =8.
