Auto Calibration Mode
The filters are automatically tuned when the ENCAL pin goes high. The filters are reset to a nominal value whenever the
ENCAL pin goes low. The auto calibration circuitry is independent of the EN WUP and the EN RX control pins.
The EN RX and ENCAL pins can be connected together if desired.
