PICC Type A,The following activation sequence shall be applied:,PICC activation sequence as defined in ISO/IEC 14443-3(request,anticollision loop and select).,At the beginning the SAK byte shall be checked for availability of an ATS.The SAK is defined in,ISO/IEC 14443-3.,The PICC may be set to HALT state,using the HLTA Command as defined in ISO/IEC 14443-3,if no ATS is,available.,The RATS may be sent by the PCD as next command after receiving the SAK if an ATS is available.The PICC shall send its ATS as answer to the RATS.The PICC shall only answer to the RATS if the RATS is,received directly after the selection.,If the PICC supports any changeable parameters in the ATS,a PPS request may be used by the PCD as the,next command after receiving the ATS to change parameters.,The PICC shall send a PPS Response as answer to the PPS request.,A PICC does not need to implement the PPS,if it does not support any changeable parameters in the ATS.,The PCD activation sequence for a PICC Type A

most significant half-byte b8 to b5 is called FSDI and codes FSD.The FSD defines the maximum size of aframe the PCD is able to receive.The coding of FSD is given in Table 1.The least significant half byte b4 to b1 is named CID and it defines the logical number of the addressed PICCin the range from 0 to 14.The value 15 is RFU.The CID is specified by the PCD and shall be unique for allPICCs,which are in the ACTIVE state at the same time.The CID is fixed for the time the PICC is active andthe PICC shall use the CID as its logical identifier,which is contained in the first error-free RATS

order:format byte T0,interface bytes TA(1),TB(1),TC(1)and historical bytes T1 to Tk.,5.2.2,Length byte,The length byte TL is mandatory and specifies the length of the transmitted ATS including itself.The two CRCbytes are not included in TL.The maximum size of the ATS shall not exceed the indicated FSD.Therefore themaximum value of TL shall not exceed FSD-2.,5.2.3,Format byte,The format byte T0 is optional and is present as soon as the length is greater than 1.The ATS can only contain thefollowing optional bytes when this format byte is present.T0 consists of three parts(see Figure 5):The most significant bit b8 shall be set to 0.The value 1 is RFU.The bits b7 to b5 contain Y(1)indicating the presence of subsequent interface bytes TC(1),TB(1)and TA(1).The least significant half byte b4 to b1 is called FSCI and codes FSC.The FSC defines the maximum size of aframe accepted by the PICC.The default value of FSCI is 2 and leads to a FSC of 32 bytes.The coding ofFSC is equal to the coding
