Most instructions are single byte (with immediate addressing mode instructions taking
two bytes).
Most single byte instructions take one cycle time to execute.
Skipped instructions require x number of cycles to be skipped, where x equals the
number of bytes in the skipped instruction opcode.
See the BYTES and CYCLES per INSTRUCTION table for details.
