23.8.1 Quick Start Guide for SYSTEM PINMUX - Basic

In this use case, the PINMUX module is configured for:

One pin in input mode, with pull-up enabled, connected to the GPIO module
Sampling mode of the pin changed to sample on demand

This use case sets up the PINMUX to configure a physical I/O pin set as an input with pull-up and changes the sampling mode of the pin to reduce power by only sampling the physical pin state when the user application attempts to read it.
