The host should select the device code, clock mode, and new bit rate with device selection, clock-
mode selection, and new bit-rate selection commands, and then send the command for the
transition to programming/erasing state. These procedures should be carried out before sending of
the programming selection command or program data.
• Command, H'40, (one byte): Transition to programming/erasing state
• Response, H'06, (one byte): Response to transition to programming/erasing state
• Error response, H'C0, (one byte): Error response for user boot MAT blank check
• Error code, H'51, (one byte): Erasing error
(7)
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, H'80, (one byte): Command error
• Command, H'xx, (one byte): Received command
(8)
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
