4.3 CORTEX M4 Crystal
For system clock generation an external crystal is mandatory. As default, a crystal with 16MHz
frequency and a frequency stability of ±50ppm should be used. Crystal frequency can be
modified for customized firmware versions. Load capacitors C1, C2 depends on the used crystal.
Values are typically in a range of 8-22pF.

4.4 Supply Filter
To ensure proper operation VM and 3.3V supply voltage must be stable. TMCC160 already
includes small buffer capacitors to stabilize the supply voltages. Nevertheless are additional
capacitors mandatory.
