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
“deasserted” Means that a high true (active high) signal is low or that a low true (active low)
signal is high
Examples:
Signal/Symbol
Logic State
Signal State
Voltage
Note:
PIN
