68000 Addressing Modes: 68000 utilizes 14 different 68000 Addressing Modes which can be grouped into 6 basic types. These are 1.Direct Register Addressing a)Data Register Direct b)Address Register Direct 2.Direct Memory Addressing a)Absolute short b)Absolute…
Motorola 68000 Pins and Signals: Fig. 11.3 illustrates the Motorola 68000 Pins and Signals. Data Transfer Control and Address Lines: D0-D15 is the bi-directional 16-bit data bus. A1-A23 is the output 24-bit address bus. The UDS…
Register Architecture of 68000 Microprocessor: Fig. 11.1 illustrate the Register Architecture of 68000 Microprocessor. Data Registers: The data registers can be used to handle (8-bit) bytes, (16-bit) words, or 32-bit long words. When a data…
Motorola 68000 Features: The Motorola 68000 microprocessor is Motorola's first 16-bit microprocessor. The 68000 is not program compatible with Motorola's family of 8-bit microprocessors. For the designing of instruction set the Motorola has given more…
Address Decoding Techniques in 8086 Microprocessor: The Different types of Address Decoding Techniques in 8086 Microprocessor are, Absolute decoding Linear decoding Block decoding 1. Absolute Decoding : In absolute decoding technique the memory chip is selected…
Memory Addressing Modes of 8086: Most of the memory ICs are byte oriented i.e. each memory location can store only one byte of data. The 8086 is a 16-bit microprocessor, it can transfer 16-bit data.…
Maximum Mode Configuration of 8086: A processor is in the Maximum Mode Configuration of 8086 when its MN/MX pin is grounded. The maximum mode defines pins 24 to 31 as follows: Pin Definitions (24 to…
Minimum Mode Configuration of 8086: Pin definitions from 24 to 31 are different for minimum mode and maximum mode. By using these pins the 8086 itself generates all bus control signals in the Minimum Mode…
8086 Microprocessor Pin Diagram and 8088 Pin Diagram: In order to implement many situations in the microcomputer system the 8086 Microprocessor Pin Diagram and 8088 Pin Diagram has been designed to work in two operating…
Interrupt Priority in 8086: As far as the Interrupt Priority in 8086 are concerned, software interrupts (All interrupts except single step, NMI and INTR interrupts) have the highest priority, followed by NMI followed by INTR.…
