Signal Conventions

Signal names are shown in all uppercase type.

All signals are either high active or low active signals. A dash character (-) at the end

of a signal name indicates that the signal is low active. A low active signal is true when

it is below ViL and is false when it is above ViH. A signal without a dash at the end

indicates that the signal is high active. A high active signal is true when it is above ViH

and is false when it is below ViL.

When a signal is asserted, it means the signal is driven by an active circuit to its true

state.

When a signal is negated, it means the signal is driven by an active circuit to its false

state.

When a signal is released, it means the signal is not actively driven to any state. Some

signals have bias circuitry that pull the signal to either a true or false state when no

signal driver is actively asserting or negating the signal. These instances are noted

under the description of the signal.
