where
Peripheral operating requirements and behaviors
⢠Writes_subsystem â minimum number of writes to each FlexRAM location for
subsystem (each subsystem can have different endurance)
⢠EEPROM â allocated FlexNVM for each EEPROM subsystem based on DEPART;
entered with Program Partition command
⢠EEESPLIT â FlexRAM split factor for subsystem; entered with the Program
Partition command
⢠EEESIZE â allocated FlexRAM based on DEPART; entered with Program Partition
command
⢠Write_efficiency â
⢠0.25 for 8-bit writes to FlexRAM
⢠0.50 for 16-bit or 32-bit writes to FlexRAM
⢠nnvmcycd â data flash cycling endurance
