⢠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.
