25. ROM (SH7059)
⎯ Minimum value of operating clock frequency (two bytes): Minimum value for each 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 multiplied by 100 to be 2000 which is H'07D0)
⎯ Maximum value of operating clock frequency (two bytes): Maximum value for each multiplied or divided clock
frequency.
There are as many pairs of minimum and maximum values as there are operating clock frequencies.
⎯ SUM (one byte): Checksum
(7) 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
Start address of area
Last address of area
…
SUM
⎯ Response: H'34 (one byte): Response to user boot MAT information inquiry
⎯ Size (one byte): Amount of data that represents the number of areas, the start address of each area, and the last
address of each area
⎯ Number of areas (one byte): Number of non-consecutive user boot MAT areas
When user boot MAT areas are consecutive, the number of areas returned is H'01.
⎯ Start address of area (four bytes): Start address of the area
⎯ Last address of area (four bytes): 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
(8) User MAT Information Inquiry
The boot program will return the number of user MATs and their addresses.
Command H'25
⎯ Command: H'25 (one byte): Inquiry regarding user MAT information
Response H'35 Size Number of areas
Start address of area
Last address of area
…
SUM
⎯ Response: H'35 (one byte): Response to the user MAT information inquiry
⎯ Size (one byte): Amount of data that represents the number of areas, the start address of each area, and the last
address of each area
⎯ Number of areas (one byte): Number of non-consecutive user MAT areas
When user MAT areas are consecutive, the number of areas returned is H'01.
⎯ Start address of area (four bytes): Start address of the area
— Last address of area (four bytes): 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
(9) Erased Block Information Inquiry
The boot program will return the number of erased blocks and their addresses.
Command H'26
⎯ Command: H'26 (one byte): Inquiry regarding erased block information
