Make sure that you include the question followed by your answer to the question in your posting. In the description of the Hack machine language in chapter 4, it is stated that in well-written programs a C-instruction that may cause a jump should not contain a reference to M, and vice versa. Discuss why this should be avoided. Research the concept of interrupts in a computer. You may want to look into how the Z80 microprocessor handles interrupt. A good source of Z80 information is Zaks, R. (1980). Programming the Z80. Sybex. Download the pdf. FYI, The Z80 8 bit microprocessor has been in production for forty years. Knowledge of the Z80 is a great lead-in for further study in more complicated machines.arrow_forward
