Peripheral operating requirements and behaviors
• EEPROM — allocated FlexNVM for each EEPROM subsystem based on DEPART;
entered with Program Partition command
• EEESPLIT — FlexRAM split factor for subsystem; entered with the Program
Partition command
• EEESIZE — allocated FlexRAM based on DEPART; entered with Program Partition
command
• Write_efficiency —
• 0.25 for 8-bit writes to FlexRAM
• 0.50 for 16-bit or 32-bit writes to FlexRAM
• n_nvmcycee — EEPROM-backup cycling endurance
