Peripheral operating requirements and behaviors
• EEPROM — allocated FlexNVM based on DEPART; entered with the Program
Partition command
• EEESIZE — allocated FlexRAM based on DEPART; entered with the Program
Partition command
• Write_efficiency —
• 0.25 for 8-bit writes to FlexRAM
• 0.50 for 16-bit or 32-bit writes to FlexRAM
• nnvmcycd — data flash cycling endurance (the following graph assumes 10,000
cycles)
