Sorry everyone. I accidentally reversed the opcode values in my first posting
|from what Z JAN said. The exact words in the email to me were:
>In [ mmc6r02g.pdf 6.15 ] and [ mmc5r04.pdf 6.16 ], the OperationCode of
READ(12) command had error value of 28h, but it should be A8h.
>The value in mmc4r05a.pdf is right.
The final working draft of MMC-4:
PDF Page 334, Table 335 - READ (12) CDB has operation code (A8h)
The final working draft of MMC-5:
PDF Page 428, Table 347 - READ (12) CDB has operation code (28h)
The final working draft of MMC-6:
PDF Page 400, Table 336 - READ (12) CDB has operation code (28h)
I think that Z JAN is correct and both MMC-5 and MMC-6 are in error.
By the way, only T10 members will be able to access the above links to the
final working drafts of the MMC standards.
