Setting the power threshold:
The reference power threshold can be easily
controlled by simply changing the value of the external
R
setting up the “reference power”. The internal R
about 30 kΩ, so the reference voltage can be
approximated by :

As mentioned, the slicer includes an internal
Hysteresis circuit that prevents the stage from
bouncing
Hysteresis envelope is about 50 mV.
Power down:
By invoking the appropriate command, the MCU can
shut down the slicer block and thereby maintain a very
low quiescent current.
