ISO15693_Add_Request_Flags_Command_code_to_command function

This function adds the Request flags into the command's data and increments the counter

of data.

Is Functions

ISO15693_Is_ResponseFlags_noError_Detected function

This function checks if the response flag is set or not. If it is set, the contactless tag

encountered an error while performing the command.

ISO15693_Is_Request_Flags_ok function

This function performs several checks to verify that the request flag is not wrong. This is not

a guarantee that the request flag is right (depends on the contactless tag and on some

command particularities).
