Signal Descriptions
Signal Terminology
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.
The following terminology is used in this chapter:
Driven—The processor actively pulls the signal up to the
High-voltage state or 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.
