6.2.1.2 Open-drain output configuration
6.2.1.3 Input-only configuration
6.2.1.4 Push-pull output configuration
The open-drain output configuration turns off all pull-ups and only drives the pull-down
transistor of the pin when the pin latch contains a logic 0. To be used as a logic output, a
pin configured in this manner must have an external pull-up, typically a resistor tied to
V
The open-drain pin configuration is shown in
An open-drain pin has a Schmitt-triggered input that also has a glitch suppression circuit.
The input-only pin configuration is shown in
also has a glitch suppression circuit.
The push-pull output configuration has the same pull-down structure as both the
open-drain and the quasi-bidirectional output modes, but provides a continuous strong
pull-up when the pin latch contains a logic 1. The push-pull mode may be used when
more source current is needed from a pin output.
The push-pull pin configuration is shown in
A push-pull pin has a Schmitt-triggered input that also has a glitch suppression circuit.
