1.1 Command Format
Control commands are of variable length in 8-bit units and are input in serial.
Three types of commands are available: 1-byte commands consisting of 8 bits of instruction and data in
combination, 2-byte commands of 16 bits of instruction and data in combination, and a 2-byte contiguous
command that can be abbreviated for input.
