1.1 Conventions

This document uses the following conventions:

• OVERBAR is used to indicate a signal that is active when pulled low: for example, RESET.

• Logic level one is a voltage that corresponds to Boolean true (1) state.

• Logic level zero is a voltage that corresponds to Boolean false (0) state.

• To set a bit or bits means to establish logic level one.

• To clear a bit or bits means to establish logic level zero.

• A signal is an electronic construct whose state conveys or changes in state convey information.

• A pin is an external physical connection. The same pin can be used to connect a number of signals.

• Asserted means that a discrete signal is in active logic state.

— Active low signals change from logic level one to logic level zero.

— Active high signals change from logic level zero to logic level one.

• Negated means that an asserted discrete signal changes logic state.

— Active low signals change from logic level zero to logic level one.

— Active high signals change from logic level one to logic level zero.

• LSB means least significant bit or bits, and MSB means most significant bit or bits. References to low and

high bytes or words are spelled out.

• Numbers preceded by a percent sign (%) are binary. Numbers preceded by a dollar sign ($) or 0x are

hexadecimal.
