Command Information
Request Information
| Byte | Data Field |
|---|---|
| NetFn | 30h |
| CMD | 92h |
| 1:3 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 4 | Sub command=50h |
| 5 | TPM/TCM Type length=T. The value ranges from 1 to 16 bytes. |
| 6:5+T | Type name , for example, TPM, TCM, and TPCM. |
| 6+T | TPM/TCM Protocol Version,length=P. The value ranges from 0 to 16 bytes. If the length is 0, the trusted module does not support the obtaining of the corresponding field. |
| 7+T:6+T+P | TPM/TCM Protocol Version information. If the length is 0, this field does not exist. |
| 7+T+P | TPM/TCM Firmware Version,length=F. The value ranges from 0 to 16 bytes. If the length is 0, the trusted module does not support the obtaining of the corresponding field. |
| 8+T+P:7+T+P+F | TPM/TCM Firmware version information. If the length is 0, this field does not exist. |
| 8+T+P+F | TPM/TCM Self-Test Result 1: success 2: fail 0xff: N/A. For example, the trusted module does not provide the capability of obtaining self-check information, or Presence is 0 (not in position). |
| 9+T+P+F | TPM/TCM Manufacturer Len: M. The value ranges from 0 to 16 bytes. If the length is 0, the trusted module does not support the obtaining of the corresponding field. |
| 10+T+P+F:9+T+P+F+M | TPM/TCM Manufacturer name. If the length is 0, this field does not exist. |
| 11+T+P+F:9+T+P+F+M | HBRT Self-Test Result 1: success 2: fail 0xff: N/A. For example, the hardware RoT does not provide the capability of obtaining self-check information, or the value of Presence is 0 (not in position). |
