Key Words

The names of abbreviations, commands, fields and acronyms used as signal names are in all uppercase type

(e.g., IDENTIFY DRIVE). Fields containing only one bit are usually referred to as the “name” bit instead of

the “name” field.

Names of drive registers begin with a capital letter (e.g., Cylinder High register).

NumberingNumbering

Numbering

Numbers that are not followed by a lowercase “b” or “h” are decimal values. Numbers that are followed by

a lowercase “b” (e.g., 01b) are binary values. Numbers that are followed by a lowercase “h” (e.g., 3Ah) are

hexadecimal values.

Signal ConventionsSignal Conventions

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.
