in word units. The length of EPC is less than 15 words, can be 0 or 15. Otherwise, it
returns the parameters error message.
EPC: Be operated tag’s EPC number. EPC length according to the decision of the EPC number, EPC
numbers in word units, and must be an integer number of lengths. High word first, the high byte of each word first.
Requirement given here is a complete EPC number.
Select: One byte, defined as follows:
0x00: Control Kill Password protection setting.
0x01: Control Access password protection setting.
0x02: Control EPC memory protection setting.
0x03: Control TID memory protection setting.
0x04: Control User memory protection setting.
Other value when error occurred.
