Overview
Data Sheet Conventions
This data sheet uses the following conventions:
OVERBAR
Used to indicate a signal that is active when pulled low (For example, the RESET pin is active
when low.)
“asserted”
Means that a high true (active high) signal is high or that a low true (active low) signal is low
Means that a high true (active high) signal is low or that a low true (active low) signal is high
“deasserted”
Examples:
