Introduction

Analyzing the Intel 80286

The HP 10312D Preprocessor Interface Module, when installed in the

HP 10269C General Purpose Probe Interface, provides a complete

interface between an 80286 target system and the HP 16SOA or

HP 16510A Logic Analyzer. The interface module connects the signals

from the 80286 target microprocessor to the logic analyzer inputs and

generates all status and clock signals required by the software for

inverse assembly of the 80286 instruction set.

The 80286 Interface Module operates in the bus mode. In the bus

mode, all bus cycles, including prefetches, are sent to the logic analyzer

as they occur. All coprocessor (80287) cycles on the local bus will also

be captured.

The 80286 configuration software on the flexible disc sets up the format

specification of the logic analyzer for compatibility with the 80286

microprocessor. It also loads the inverse assembler routine for

obtaining displays of 80286 data in assembly language mnemonics. The

interface module specifications are given in chapter 2.
