Intersil 80C86 Microprocessor User Manual
This manual describes the Intersil 80C86 16‑bit CMOS microprocessor, its features, static operation, internal architecture, and memory organization. It covers the processor's ability to operate from DC up to 8 MHz, low‑power modes, and the instruction queue mechanism.
Detailed pin descriptions for both minimum and maximum mode systems are provided, along with bus operation timing, signal definitions (BHE, RD, INTR, etc.), and the functional behavior of control lines such as RESET, LOCK, and ALE. The document also includes functional diagrams and timing information for bus cycles.

Questions answered in these manuals
What is the purpose of the BHE pin?
BHE (Bus High Enable) selects the upper half of the data bus for transfers, allowing access to the high byte of a word.
How is the RESET pin activated?
RESET is triggered by a transition from LOW to HIGH that remains HIGH for at least four clock cycles, causing the processor to restart.
