RxMultiple If set to 0, the receiver is deactivated after receiving the Datastream.
If set to 1, it is possible to receive more than one Frame.
5
ZeroAfterColl If set to 1, any bits received after a bit-collision are masked to zero. This eases
resolving the anti-collision procedure defined in the standard ISO 15693.
