The entire capacity size = 8 KB.
[Description] Stores the data (d1...dk) as the record specified by the key codes (c1, c2) in the NV
user memory.
[d1...dk] specify the stored data (contents of the record).
[Note] If the number of data ((pL + pH × 256) – 5) exceeds the remaining capacity of the NV
user memory, this function does not work.
