certainly be needed. When two or more selection commands are transmitted at once, the last
command will be valid.
All of these commands, except for the boot program status inquiry command (H'4F), will be valid
until the boot program receives the transition to programming/erasing state command (H'40). The
host can select the needed commands out of the commands listed above and inquire them. The
boot program status inquiry command (H'4F) is valid after the boot program has received the
transition to programming/erasing state command (H'40).
(a) Supported Device Inquiry
The boot program will return the device codes of supported devices and the product name in
response to the supported device inquiry.
Command
Response
• Command, H'20, (one byte): Inquiry regarding supported devices
• Response, H'30, (one byte): Response to the supported device inquiry
• Size (one byte): Number of bytes to be transferred, excluding the command, size, and
• Number of devices (one byte): The number of device types supported by the boot program
• Number of characters (one byte): The number of characters in the device codes and boot
• Device code (four bytes): ASCII code of the supported product name
• Product name (n bytes): Type name of the boot program in ASCII-coded characters
• SUM (one byte): Checksum
• The checksum is calculated so that the total number of all values from the command byte to
checksum, that is, the amount of data consists of the number of devices, characters, device
codes, and product names
program’s name
the SUM byte becomes H'00.
