		xxxxh	It is.	Execution. **

	Excluding 01h and 07h	−		Abort

**: 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.

Table 5.6 Example of rewriting procedure of data 384 KBytes (30000h Bytes) of microcode

Transfer example 1:
1)	CMD = 92h SN, SC = 0100h		FR = 0lh	Transfer of 127 KB from the first
2)	CMD = 92h SN, SC = 0100h		FR = 0lh	Transfer from 128 to 255 KB
3)	CMD = 92h SN, SC = 0100h		FR = 0lh	Transfer from 256 to 383 KB
4)	CMD = 92h SN, SC = 0000h		FR = 07h	Firmware rewriting execution

Transfer example 2:
1)	CMD = 92h SN, SC = 0300h		FR = 0lh	Transfer of 384 KB
2)	CMD = 92h SN, SC = 0000h		FR = 07h	Firmware rewriting execution

Transfer example 3:
1)	CMD = 92h	SN, SC = 0300h	FR = 07h	Transfer of 384 KB and Firmware rewriting
				execution

Transfer example 4:
1)	CMD = 92h	SN, SC = 0100h	FR = 0lh	Transfer of 127 KB from the first
2)	CMD = 92h	SN, SC = 0100h	FR = 0lh	Transfer from 128 to 255 KB
3)	CMD = 92h	SN, SC = 0100h	FR = 07h	Transfer from 256 to 383 KB and Firmware
				rewriting execution

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.
