No Field Name

6 Register Data 2 (high byte)

Notice the data from fourth to seventh. The Read data (Register Data 1, 2) are subject to Endian function.
(As for the data arrangements of Special Endian, please refer to "[2] How data are arranged by each
endian.")
As you have seen in these examples, Endian function is applied not only to the data in Query but also to
the data in Response. Therefore, aside from when necessary, Response examples will be left out henceforth.
