Example of processing
Example 1)
● Five pieces (five words) of 16-bit BIN data are read from the file "\abc\data1.bin" in an SD
memory card, and the data pieces are stored in the area starting with DT102.
● As the “Reading position specification mode 1” is selected, the file pointer moves after
reading.
