scope:

This part of ISO/IEC 11889 contains the definitions of the constants, flags, structure, and union definitions used to communicate with the TPM. Values defined in this part of ISO/IEC 11889 are used by the TPM commands defined in ISO/IEC 11899-3 and by the functions in ISO/IEC 11889-4. NOTE The structures in this document are the canonical form of the structures on the interface. All structures are "packed" with no octets of padding between structure elements. The TPM-internal form of the structures is dependent on the processor and compiler for the TPM implementation.
