50.10.5.4 Data Area Information Inquiry
Size (1 byte): Total bytes of data of Number of areas, Area start address, and Area end address (the value is always 09h)
Number of areas (1 byte): Number of areas in the data area (the value is always 01h)
Area start address (4 bytes): Start address of the data area (the value is always 0010 0000h)
Area end address (4 bytes): End address of the data area (the value is always 0010 1FFFh)
SUM (1 byte): Value that is calculated so the sum of the response data is 00h (the value is always 7Dh)
50.10.5.5 Block Information Inquiry
When the MCU receives this command, it sends the start address, the size of one block, and the number of blocks in the
user area and data area.
Size (2 bytes): Total bytes of data from DDh to Number of blocks of the data area (the value is always 00 19h)
Start address of the user area (4 bytes): Start address of the user area
Block size of one block for the user area (4 bytes): Memory size of one block (the value is always 00 00 08 00h)
Number of blocks of the user area (4 bytes): Number of blocks in the user area
Start address of the data area (4 bytes): Start address of the data area (the value is always 00 10 00 00h)
Block size of one block for the data area (4 bytes): Memory size of one block (the value is always 00 00 04 00h)
Number of blocks of the data area (4 bytes): Number of blocks in the data area (the value is always 00 00 00 08h)
SUM (1 byte): Value that is calculated so the sum of response data is 00h
When the MCU receives this command, it sends the number of data areas and addresses.
