- 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.
