INTRODUCTION

The M80C286 is an advanced 16 bit CHMOS III microprocessor designed for multi-user and multi-tasking applications that require low power and high performance. The M80C286 is fully compatible with its predeces sor the HMOS M80286 and object-code compatible with the M8086 and M80386 family of products. In addition, the M80C286 has a power down mode which uses less power, making it ideal for mobile applications. The M80C286 has built-in memory protection that maintains a four level protection mechanism for task isolation, a hardware task switching facility and memory mangement capabilities that map 230 bytes (one gigabyte) of virtual address space per task (per user) into 224 bytes (16 megabytes) of physical memory.
