3.9. CFG8 + CFG9 : Selection Mask (only I-Code EPC Transponder)
The I-Code EPC Transponder supports a selection feature in which groups of Transponders may be
selected. The parameters in this configuration block define the selection mask. Only the Transponders
in which the selection mask match with the serial number return their serial number.

SELECTION BITS:
Defines the number of bits for the selection mask. If 0, no selection take place. The advan-
tage of the selection is that the Transponder communication time is speeded up. The maxi-
mum number of bits is 152 (=0x98)
SELECTION MASK:
Defines the mask for the selection (MSB first). The selection mask is checked against the
memory content (I-Code EPC and UID) on a bit by bit basis.
