Short Description
The modulation now changes at each bit boundary.
If the tag is selected by a group select command which was sent before an
anticollision command, the anticollision command will now based on this selection.
The read and program commands which follow will not; they wil be based only on
the selection of the arbitration result.
Both I/O pads are now usable in both directions.
