the needed commands out of the commands and inquiries listed above. The boot program status
inquiry command (H'4F) is valid after the boot program has received the programming/erasing
transition command (H'40).
(a) Supported Device Inquiry
The boot program will return the device codes of supported devices and the product code in
response to the supported device inquiry.
Command
• Command, H'20, (1 byte): Inquiry regarding supported devices
Response
• Response, H'30, (1 byte): Response to the supported device inquiry
• Size (1 byte): Number of bytes to be transmitted, excluding the command, size, and checksum,
• Number of devices (1 byte): The number of device types supported by the boot program
• Number of characters (1 byte): The number of characters in the device codes and boot
• Device code (4 bytes): ASCII code of the supporting product
• Product name (n bytes): Type name of the boot program in ASCII-coded characters
• SUM (1 byte): Checksum
(b) Device Selection
The boot program will set the supported device to the specified device code. The program will
return the selected device code in response to the inquiry after this setting has been made.
Command
• Command, H'10, (1 byte): Device selection
• Size (1 byte): Amount of device-code data
• Device code (4 bytes): Device code (ASCII code) returned in response to the supported device
• SUM (1 byte): Checksum
that is, the amount of data contributes by the number of devices, characters, device codes and
product names
program’s name
The checksum is calculated so that the total number of all values from the command byte to
the SUM byte becomes H'00.
