[1] The marked levels on this pin are correlated. The voltage difference between the levels has much less spread than the absolute value of
the levels themselves.
[2] Switching level has some hysteresis. The hysteresis falls within the limits.
[3] For a typical application with a compensation network on pin COMPPFC, like the example in Figure 17.
[4] Minimum required voltage change time for valley recognition on pin SNSAUXPFC.
[5] Minimum time required between demagnetization detection and V/t = 0 on pin SNSAUXPFC.
