**: In the following cases, Subcommand code=07h returns Abort as an error though becomes Microcode rewriting execution specification.
1)Abnormality of the transmitted Microcode data is detected.
2)The data transfer is not done (The number of transfer: 0).
3)"DOWNLOAD MICROCODE" The command is not continuously issued.

When the data of the transfer microcode did the rewriting specification with the illegality and the data transfer not done or the DOWNLOAD MICROCODE command is not continuously issued, reports on the Aborted Command error.
