The data mask supplies the filter of EPC data. The “Mask” field is the bytes of filter; the “Mask
Length” is the number of bits to filter. When the “Mask Length” is zero, the “Mask” is meaning
nothing (see Fig. 17). For example, in order to read EPC code which started bytes are “A1A0”, the
“Mask” filed must be input as “A1A0” and “Mask Length” field must be “0x10” bits.
