[2] How data are arranged in each endian.
The following charts show example of how Endian works with data in a 16-bit Holding register and in a
32-bit register (=two consecutive Holding registers given the same parameter name)
1) In the case of 16-bit registers
Example ） 1 6-bit data = 0102h

In the case of Big Endian, high order byte of 16-bit data is stored in the Holding register first, followed by
low order byte of the 16-bit data.
In the case of Little Endian, low order byte of 16-bit data is stored in the Holding register first, followed by
the high order byte of the 16-bit data.
Special Endian works the same as Big Endian does for 16-bit Holding registers. Because Special Endian
works in the unit of two bytes, no change involves for data in 16-bit Holding registers.
