Comments / Signal routing
reverse battery protection
Close (<5mm) to VSUP1, VSUP2 pins with good ground return
Close (<3mm) to digital supply pins (EVDD, EVSS) with good ground
return.
The positive analog (VREFH, VDDA) and the digital (EVDD) supply
should be connected right at the C3.
Bulk Capacitor
Close (<5mm) to LIN pin.
Total Capacitance on LIN has to be below 220pF.
