Example 2) Reading multiple parameters (motor ID(Address: 0x2000), Encoder
Type(Address: 0x2001), number of encoder pulses per rotation (Address:
0x2002~0x2003))

- motor ID (Address: 0x2000) value reads 13(or 0x000D), and Encoder type (Address:
0x2001) value reads 2(or 0x0002). Number of encoder pulses per rotation (Address:
0x2002~0x2003) is a 32bit data, so the data must be swapped once read. Thus, the
currently displayed value 524288 (or 0x00080000).
