bytes from the head of the stored file.
● In the case of writing position specification mode 1, when completing
writing to an SD memory card, the end position of the newly-saved data
counting from the head of the file is stored in the areas [D2+3] and [D2+4].
● In the case of writing position specification mode 2, when completing
writing to an SD memory card, the end position of the newly-saved data
counting from the end of the file is stored in the areas [D2+3] and [D2+4].
D2+4
D2+5
Number of written
data
Stores the number of data items that could be written after writing to the file.
