Anticollision for CL1 (Short-cut) and CL2
The SLE 66R35E7 supports the both anticollision schemes cascade level 1 (short-cut anticollision) and 2. The
short-cut anticollison allows to operate the SLE 66R35E7 even in infrastructures with 4-byte (single cascade)
anticollision scheme. Existing systems based on CL1 can remain unchanged.
If the Short-cut anticollision scheme has been enabled (UIDF1 Option, see
state the chip accepts:
