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

A programming selection command makes the boot program select the programming method, an
128-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 in table 23.10.
