or a command is unacceptable. Issuing a clock mode selection command before a device selection
command, or an inquiry command after the transition to programming/erasing state command, are
such examples.

(8) 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
with a device selection (H'10) command.
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
and set.
5. After selection of the device and clock mode, inquiries for other required information should
be made, such as the division ratio inquiry (H'22) or operating frequency inquiry (H'23), which
are needed for a new bit rate selection.
6. A new bit rate should be selected with the new bit rate selection (H'3F) command, according to
the returned information on division ratios and operating frequencies.
7. After selection of the device and clock mode, programming/erasing information of the user
boot MAT and user MAT should be inquired using the user boot MAT information inquiry
(H'24), user MAT information inquiry (H'25), erased block information inquiry (H'26), and
programming unit inquiry (H'27).
