221 Active-low State and Raw GPIO Values
226 following set of calls ignore the active-low property of a GPIO and work on the
235 The active-low state of a GPIO can also be queried using the following call:
243 The active-low property
248 the *logical* value. With this they take the active-low property into account.
249 This means that they check whether the GPIO is configured to be active-low,
