The stack a. Is an area of ROM used for the retrieval of information, typically tables and codes b. Is an area of RAM used for the temporary storage and retrieval of information, typically the MPU's internal registers c. Is an area of RAM used for the storage of a program to be executed at some future time d. is an area of ROM used for controlling I/O interfacing Last-in, first-out describes the operation of a. RAM b. ROM C. Stack d. ALU The stack pointer is incremented and decremented a. By the programmer in his or her main program b. By MPU each time data are placed on or taken off the stack c. By external logic circuits each time a READ operation is performed d. By external logic circuits each time a WRITE operation is performed Which of the following is an ALU single-operand instruction? a. ADD b. COMPARE c. AND d. NEGATE True or False: a. All microcomputers are microcontrollers b. All microcontrollers are microcomputers The COP reset was designed to monitor and detect hardware errors. (True/False) An accumulator can be used as a storage register for data that are being sent to an output device or as a receiving register for data that are being read from an input device (True/False) Index register a. Performs arithmetic operations b. Indicate the sign of the results of any arithmetic, data manipulation or data transfer operation c. Can be used for general MPU storage functions and as a counter d. Performs STOP instructions being executed Major function of Timing & Control section is to fetch and decode instructions from program memory (True/False)
