6.6.14. MIC Variable Length Information Page (Sony Unique)
Page 3Eh is a variable length page. That is not defined by ANSI. This page is Sony Vendor Unique.
Important NOTE:
1. Only one Parameter Code in Page 3Eh is transferred at a time.
2. Byte position 3 of Parameter Code in the Page 3Eh is Reserved. (Should be set to ZERO.)
3. Parameter Length for the contents of the Parameter Code in Page 3Eh is stored at the byte position 4 and 5.
4. The Page Length field in the Page Code indicates the total number of bytes that follow this byte. This value is
independent of what is specified for the Allocation Length in the CDB.

Note:
1. If there is no Note data in MIC for the Parameter Code specified in the CDB a Check Condition status will be
returned.
2. If the CDB allocation length is ZERO a Good status is always returned and there is no data phase.
3. If the CDB allocation length is non-ZERO and there is data in MIC for the Parameter Code data will be returned
up to the size of the MIC data, as limited by the allocation length. For example, if the CDB allocation length is
0FFh and MIC data size for the Parameter Code is 020h 020h data will return. If the CDB allocation length is
010h and the MIC data size for the Parameter Code is 020h only 010h data will be returned.
