Digital power ground

1) For best results keep the crystal circuitry connections as short as possible and keep the CLKOUT

line away from it.

2) If the bus lines work according to the ISO specification, additional circuitry is necessary for

interconnection of the input comparator to the bus lines.

The digital mode is enabled by setting bit DI in register BL2. When using the digital mode pin RX1

should be on VSS.

3) It is recommended to decouple these supply pins close to the device using a 10 pF capacitor in

addition to the standard 100 nF capacitor.
