• Minimum value of operating clock frequency (two bytes): The minimum value of the
multiplied or divided clock frequency.
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.)
• Maximum value (two bytes): Maximum value among the multiplied or divided clock
frequencies.
There are as many pairs of minimum and maximum values as there are operating clock
frequencies.
• SUM (one byte): Checksum
(g) User Boot MAT Information Inquiry
The boot program will return the number of user boot MATs and their addresses.
Command H'24
• Command, H'24, (one byte): Inquiry regarding user boot MAT information
Response
H'34 Size Number of areas
Area-start address
···
SUM
Area-last address
• 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 addresses,
and area-last address
• Number of Areas (one byte): The number of consecutive user boot MAT areas
When user boot MAT areas are consecutive, the number of areas returned is H'01.
• Area-start address (four byte): Start address of the area
• Area-last address (four byte): Last address of the area
There are as many groups of data representing the start and last addresses as there are areas.
• SUM (one byte): Checksum
