MBL80286-6 16-Bit Microprocessor

The following pin function descriptions are for the MBL 80286 microprocessor: Table 1 - PIN DESCRIPTION Symbol Type Name and Function ClK I System Clock provides the fundamental timing for MBl 80286 systems. It is divided by two inside the MBl80286 to generate the processor clock. The internal divide-by-two circuitry can be synchronized to an extern.

Features

MBL 80286 is source code compatible with MBl8086, 88 software and may require upgrading to use virtual addresses supported by the MBL 80286's integrated memory management and protection mechanism. Both modes operate at full MBl 80286 performance and execute a superset of the MBL 8086 and 88's instructions. The MBL 80286 provides special operations to support the efficient implementation and execution of operating systems. For example, one instruction can end execution of one task, save its state, switch to a new task, load its state, and start execution of the new task. The MBl 80286 also su.
