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.
