3.4.2.
The following parameters are determined with short-cut between the pins ASIN, GND, and 0V (GROUND).
The pin VIN is connected to ASIP via an external coil. A decoupling capacitor has to be interconnected
between VIN and GROUND as shown in Figure 4-1.

3.4.3.
The on chip x-tal oscillator requires a 16 MHz crystal that must be interconnected to the pins OSC1 and
OSC2. Internal capacitors make sure that no external capacitors from OSC1/OSC2 to ground are required.
Furthermore no external capacitors shall be added to OSC1 and OSC2, respectively. Due to this parasitic
capacitors shall be limited to C
supposed to be used in A²SI-L IC application circuits.
