Section 20 Flash Memory
(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, 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 transmitted, 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 supporting product
• Product name (n bytes): Type name of the boot program in ASCII-coded characters
• SUM (one 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, H'10, (one byte): Device selection
• Size (one byte): Amount of device-code data
• Device code (four bytes): Device code (ASCII code) returned in response to the supported
