Every supply pair must be decoupled by a ceramic capacitor connected as near as
possible to the corresponding pins(C1 - C6).
Central point of the ground star should be the VSSR pin.
Use low ohmic low inductance connections between VSS1, VSS2 and VSSR.
VSSPLL must be directly connected to VSSR.
Keep traces of VSSPLL, EXTAL and XTAL as short as possible and occupied board area
for C7, C8, C11 and Q1 as small as possible.
Do not place other signals or supplies underneath area occupied by C7, C8, C10 and Q1
and the connection area to the MCU.
Central power input should be fed in at the VDDA/VSSA pins.
