DATA CARRIER HAVING ADDRESS MODE EXTENSION MEANS AND COMMAND EXTENSION MEANS

摘要

A data carrier (1) for the communication of transmission information (UI) to communication station (2), including program memory means (9) for the storage of a program code (PC) including instruction information (II) and associated address information (AI) in at least one program code line (PCZ), and including data memory means (10) for the storage of data information (DI) and including computing means (8) for the execution of the stored program code (PC) in order to process the communicated transmission information (UI), where for each program code line (PCZ) address mode information (AAI) included in the instruction information (II) and the associated address information (AI) can be determined and can be processed in order to access a memory location of the program memory means (9) or the data memory means (10), now includes address mode extension means (12), which in the presence of specific address information (AI) are adapted to determine stored additional address mode information (ZAAI) which identifies an additional address mode, by means of which additional address information (ZAI) can be determined, which additional address information (ZAI) can be processed by the address mode extension means (12) in order to access a memory location of the program memory means (9) or of the data memory means (10).
