Preliminary Information

Signal Descriptions

This chapter includes a detailed description of each signal

supported on the AMD-K6-2E processor. This chapter also

provides tables listing the signals grouped by type, beginning

on page 130.

The logic symbol diagram on page 83 shows the signals grouped

by function.

Connection diagrams and pins listed by high-level function are

included in Chapter 17, “Pin Designation Diagrams” on page

299.

Signal Terminology

The following terminology is used in this chapter:

Driven—The processor actively pulls the signal up to the

High-voltage state

pulls

the signal

down

to the

Low-voltage state.

Floated—The the signal is not being driven by the processor

(high-impedance state), which allows another device to

drive this signal.

Asserted—For all active-High signals, the term asserted

means the signal is in the High-voltage state. For all

active-Low signals, the term asserted means the signal is in

the Low-voltage state.

Negated—For all active-High signals, the term negated

means the signal is in the Low-voltage state. For all

active-Low signals, the term negated means the signal is in

the High-voltage state.

Sampled—The processor has measured the state of a signal

at predefined points in time and will take the appropriate

action based on the state of the signal. If a signal is not

sampled by the processor, its assertion or negation has no

effect on the operation of the processor.
