• Command, H'25, (one byte): Inquiry regarding user MAT information
• Response, H'35, (one byte): Response to the user MAT information inquiry
• Size (one byte): The number of bytes that represents the number of areas, area-start address
• Number of areas (one byte): The number of consecutive user MAT areas
• Area-start address (four bytes): Start address of the area
• Area-last address (four bytes): Last address of the area
• SUM (one byte): Checksum
• Command, H'26, (one byte): Inquiry regarding erased block information
• Response, H'36, (one byte): Response to the erased block information inquiry
• Size (two bytes): The number of bytes that represents the number of blocks, block-start
• Number of blocks (one byte): The number of erased blocks
• Block start address (four bytes): Start address of a block
and area-last address
When the user MAT areas are consecutive, the number of areas is H'01.
There are as many groups of data representing the start and last addresses as there are
areas.
