RxMultiple
If set to 0, after receiving of the Frame the receiver is deactivated
If set to 1, it is possible to receive more than one Frame
5
ZeroAfter Coll ^{If set to 1, any bits received after a bit-collision are masked to zero. This eases}
resolving the anti-collision procedure defined in ISO14443-A.
