The datarate and contactless tag response format are also defined in the request flag byte

of each command. The user application must ensure that the datarate and subcarrier flags

match the CR95HF_ProtocolSelect function parameters. This check is performed by the

ISO/IEC 15693 layer functions. If the parameters do not match, the functions are not

executed and the corresponding commands are not sent to the CR95HF.

LRIxK layer commands

LRIxK devices are compliant with ISO/IEC 15693 specification. Thus the LRIxK functions

call the ISO/IEC 15693 functions. Furthermore the LRIxK functions carry out some

additional check and modifies some parameter as defined in the LRIxK datasheet.

The table below shows the relationship between LRIxK and ISO/IEC 15693 layers. The

"function name" column presents the LRIxK functions.

The next column gives the functions called in the ISO15593 layer. If the function does not

exist in the ISO/IEC 15693 layer, the cell is empty.
