(g) User Boot MAT Information Inquiry
The boot program will return the number of user boot MATs and their addresses.
Command
Response
• Maximum value (two bytes): Maximum value among the multiplied or divided clock
• SUM (one byte): Checksum
• Command, H'24, (one byte): Inquiry regarding user boot MAT information
• Response, H'34, (one byte): Response to user boot MAT information inquiry
• Size (one byte): The number of bytes that represents the number of areas, area-start
• Number of Areas (one byte): The number of consecutive user boot 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
The minimum and maximum values represent the values in MHz, valid to the hundredths
place of MHz, and multiplied by 100. (e.g. when the value is 20.00 MHz, it will be 2000,
which is H'07D0.)
frequencies
There are as many pairs of minimum and maximum values as there are operating clock
frequencies.
addresses, and area-last address
When user boot MAT areas are consecutive, the number of areas returned is H'01.
There are as many groups of data representing the start and last addresses as there are
areas.
