Zusammenfassung:	The present disclosure relates to a rotary steerable tool operable to steer a drill bit for drilling a wellbore. In some embodiments, the rotary steerable tool is operable in an acknowledgment mode to confirm receipt of a downlink transmission by performing a detectable acknowledgement action that continues to rotate the drill bit, but temporarily suspends the steering of the drill bit for a period of time by maintaining the valve motor in a stationary rotational position relative to the valve.
