After data transmission, the activation of the receiver is delayed for
RxWait bit-clocks. During this ‘frame guard time’ any signal at pin Rx is
ignored.This parameter is ignored by the receive command.
All other commands (e.g. Transceive, MFAuthent) use this parameter.
The counter starts immediately after the external RF field is switched on.
