2.2.2 Supply of Clocks to the evaluation Chip
2.3.2.1 Configuration of Main Clock Supply
In case a crystal is used for the clock supply, it is highly recommended to use the crystals
mounted on the emulator system. Otherwise clocks might not work correctly.
The mounting of the main crystal is done in SC4 and is shown in the next figure. For the
capacitors mostly 22pF or 33pF are preferred values.
Figure 2.3.2.1.1 Crystal Mounting Example
To define the usage of the main and sub-clock pins the settings of SW3 and S7 must be
checked. The following schematic show the crystal peripheral circuit.
