ACOLL:
This bit activates Anticollision Mode. In Anticollision Mode the Reader automatical-
ly sets Transponder-specific communication parameters.
b0:
disabled
In this case the Reader doesn’t process any anticollision procedure with
the Transponders inside the antenna field.
If anticollision is disabled, the Reader automatically selects the Trans-
ponder. The Select command [0x25] is not necessary for further commu-
nication with the Transponder.
If more than one Transponder of the same type is in the detection range
the Reader replies an error status.
b1:
enabled (default)
In this case the Reader processes the anticollision procedure with the
Transponders inside of the antenna field and replies the UID of all de-
tected Transponder's.
AORB_REQ:
This parameter defines the abort conditions of the Inventory command [0x01] for
ISO14443 Transponder if the ISO14443A and ISO14443B Transponder drivers are
activated.
