NOTE
Represent an current value by 4 bytes of Hex .Lower bytes are in the front location,
higher bytes are in the later location.1 represent 0.1mA,If setting upper limit is
3.0000A，the hex code is 0X00007530，then the 4th byte is 0X30，5th is 0X75，6th
is 0X00，7th is 0X00。

NOTE
Represent power value by 4 bytes of Hex. Lower bytes are in the
Front location, higher bytes are in the later location. 1 represents 1mW. If setting
upper value is 200.000W，the hex code is 0X00030d40，then the 4th byte is
0X40，5th is 0X0d，6th is 0X03，7th is 0X00。
