2.2 Crystal
oscillator
The SPC560B-DIS board could be populated either with 8 or 16 MHz crystal to clock the
SPC560B54L5.
Default configuration is with 16 MHz crystal.

2.3 Reset
section
In order to generate a clean reset signal for the microcontroller, STM6315RDW13F is used.
SW1 button triggers such device generating a reset signal.
D8 is powered on as soon as reset pulse is generated.
The reset signal can be propagated to the on board linear voltage regulator via
RESET_ASD line closing the jumper J14 (see
Figure 3: +5 V supply section
).
