Variants

Updated

Indicates the polled value is ready for reading. Either this is the first read, or the value has changed since the last read.

Unchanged

Pending

Indicates the polled value is not ready for reading, but has been queued for recalculation. The output value will eventually switch to Updated or Unchanged.
