NFC-F TechnologyRequirements 92: FDT F,POLL,MINPoll Mode6.7.2.1 Except for the SENSF_RES, followingthe end of a Listen Frame, the NFCForum Device MUST wait at leastFDT F,POLL,MIN before transmitting theSoF of a new Poll Frame.For the SENSF_RES, following theend of the time slot specified in theSENSF_REQ, the NFC Forum DeviceMUST wait at least for a timeFDT F,POLL,MIN before transmitting theSoF of a new Poll Frame.Listen Mode6.7.2.2 The NFC Forum Device MUST beready to receive the SoF of a newPoll Frame no later thanFDT F,POLL,MIN after the ListenFrame.If the SoF of a Poll Frame is received beforeFDT F,POLL,MIN , then the NFC Forum DeviceMAY treat this as a Transmission Error.A specific value for FDT F,POLL,MIN is defined for the re-activation of the NFC Forum Device inListen Mode following a DSL_RES Response (see Section 14.9.2) or an RLS_RES Response(see Section 14.10.2).Requirements 93: FDT F,REACTIVATIONPoll Mode6.7.2.3 Following the end of a DSL_RESResponse or a RLS_RES Response,the NFC Forum Device MUST waitat least for FDT F,REACTIVATION beforetransmitting the start of a new PollFrame.Refer to Appendix A.3 for the valueof FDT F,REACTIVATION .Listen Mode6.7.2.4 The NFC Forum Device MUST beready to receive the start of a newPoll Frame no later thanFDT F,REACTIVATION after the end of aDSL_RES Response or a RLS_RESResponse.If the start of a new Poll Frame is receivedbefore FDT F,REACTIVATION , then the NFC ForumDevice MAY treat this as a Transmission Error.NOTERequirement 6.7.2.3 only applies for Initiator and not for Reader/Writer. InReader/Writer mode, re-activation of a Type 3 Tag Platform is done by means of aReset as defined in [ANALOG].Requirement 6.7.2.4 applies for Target and not for Type 3 Tag (emulation).NFC Digital Protocol Page 86
