- inverse wire-OR on an I/O line, for example a GPIO line, making it possible
for any driving stage on the line to drive it low even if any other output
to the same line is simultaneously driving it high. A special case of this
is driving the SCL and SCA lines of an I2C bus, which is by definition a
is driving the SCL and SDA lines of an I2C bus, which is by definition a
wire-OR bus.
Both usecases require that the line be equipped with a pull-up resistor. This
