Command Error
A command error will occur when a command is undefined, the order of commands is incorrect,
or a command is unacceptable. Issuing a clock-mode selection command before a device selection
or an inquiry command after the transition to programming/erasing state command, are examples.
Error
Response
• Error response, H'80, (1 byte): Command error
• Command, H'xx, (1 byte): Received command
Command Order
The order for commands in the inquiry selection state is shown below.
(1) A supported device inquiry (H'20) should be made to inquire about the supported devices.
(2) The device should be selected from among those described by the returned information and set
(3) A clock-mode inquiry (H'21) should be made to inquire about the supported clock modes.
(4) The clock mode should be selected from among those described by the returned information
(5) After selection of the device and clock mode, inquiries for other required information should
(6) A new bit rate should be selected with the new bit-rate selection (H'3F) command, according to
(7) After selection of the device and clock mode, the information of the user boot MAT and user
(8) After making inquiries and selecting a new bit rate, issue the transition to programming/erasing
Programming/Erasing State
A programming selection command makes the boot program select the programming method, an
n-byte programming command makes it program the memory with data, and an erasing selection
command and block erasing command make it erase the block. The programming/erasing
commands are listed below.
