[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 ((

pH
× 256) – 5) exceeds the remaining capacity of the NV
user memory, this function does not work.
