2.3 Operating Modes
The following table summarizes the modes of o peration of the RFIC. In general, any given mode of operation may be classified as an
Active mode or a Power Saving mode. The table indic ates which block(s) are enabled (active) in each corresponding mode. With the
exception the Shutdown mode, all can be d ynamically sele cted by sending the appropriate commands over the SPI in order to
optimize the average curre nt consumption. An “X” in any cell me ans tha t in th e giv en mode of opera tion tha t block can be
independently programmed to be either ON or OFF, without noticeably affe cting the cu rrent cons umption. The SPI circuit b lock
includes the SPI interface and the Register Space. The 32kHz OSC circuit block includes the 32.768KHz RC oscillator or 32.768KHz
Crystal O scillator, and W ake-Up-Timer. AUX (Aux iliary B locks) includes the Temperatu re Sensor, General Purpose ADC, and Low-
Battery Detector.
