Signal/Symbol
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 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.
Deasserted 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 on to logic level zero.
LSB means least significant bit or bits. MSB means most significant bit or bits. References to low
and high bytes or words are spelled out.
