Command (1 byte): Inquiry, selection, programming, erasure, checking, etc.



Response (1 byte): Response to an inquiry



Size (one or two bytes): The length of data for transfer, excluding the command/response
code, size, and checksum.



Data (n bytes): Particular data for the command or response



Checksum (1 byte): Set so that the total sum of byte values from the command code to the
checksum and change lower one byte to H'00.
