Exceptions Types of Motorola 68000: Exception means an interrupt processing. Like 8086, Exceptions Types of Motorola 68000 also uses a jump vector table to transfer program control to the appropriate handler program, whenever an exception…
Motorola 68000 Instruction Set: There are actually 56 basic instructions provided in the Motorola 68000 Instruction Set. With 14 addressing modes, 56 instructions, and 5 data types, the 68000 includes more than 1000 opcodes. The…
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-A23Â 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…
