All of these commands, except for the boot program status inquiry command (H'4F), will be valid
until the boot program receives the programming/erasing transition (H'40). The host can choose
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).
(1) Supported device inquiry
The boot program will return the device codes of supported devices and the product code of the
F-ZTAT 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, amount of data, and
• A number of devices (1 byte): The number of device types supported by the boot program
• A number of characters (1 byte): The number of characters in the device codes and boot
• Device code (4 bytes): Code of the supporting product
• Product name (n bytes): Type name of the boot program in ASCII-coded characters
• SUM (1 byte): Checksum
(2) 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
checksum, that is, the amount of data contributes by the product names, the number of devices,
characters, and device codes
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.
This is fixed to 4
