For example, in a 32-bit instruction the most significant eight bits might be the op code giving 256 possible operations. For some instruction sets, certain values in the fixed bit positions may select a group of operations and the exact operation may depend on other bits within instruction word or subsequent words. When programming in assembly language, the op code is represented by a readable name called an instruction mnemonic.
