createIBlock

public static T1Block createIBlock(int sourceID,
                                   int destID,
                                   int edcAlg,

                            throws T1Exception

createIBlock creates I-Block according to ISO7816-3

Parameters:

sourceID - the sourceID of the frame for the NAD-byte (0-7)

destID - the destID of the frame for the NAD-byte (0-7)

edcAlg - the used algorithm for calculation of the EDC byte possible values: T1Block.USE_LDR, T1Block.USE_CRC

sendSequenceNumber - the sequence number of the frame internal used value is (sendSequenceNumber mod 2)

moreDataBit - true for chained block (not implemented), false for normal operation

data - application data
