Overview

Data Sheet Conventions

This data sheet uses the following conventions:

OVERBAR

“asserted”

“deasserted”

Used to indicate a signal that is active when pulled low (For example, the RESET pin is active

when low.)

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
