Command parameter3: 1byte LEN, the length of MASK (unit: bit).
Command parameter4: m bytes, Mask. If LEN％8=0, then m=LEN/8. If
LEN％8≠0, then m=LEN/8+1.
Command packet:『40H m+7 EEH address mem addr LEN Mask
CheckSum』
Return data: if success, byte count of return data= number of all listed tags
M(1byte)+ data of (tag number sent out L(<=8)*L(digit count of
EPC+EPC)).
Note: LEN=0, to identify all readable tag ID in antenna radiation
field.
Digit count of EPC:00H-0Word，01H-1Word，02H-2Word，……，FFH-256Word
『F0H 4+L*N EEH address M L*N CheckSum』
