9.2.2.2 Input-only configuration
9.2.2.3 Push-pull output configuration
The input-only port configuration has no output drivers. It is a Schmitt triggered input that
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 port latch contains a logic 1. The push-pull mode may be used when
more source current is needed from a port output. A push-pull port pin has a Schmitt
triggered input that also has a glitch suppression circuit.
