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