1. Supply the processor in low current mode.
2. According to SPI setting and DIR.
3. Unless disabled by SPI.
4. The bus state is internally stored when going to standby mode. A change of bus state will lead to a wake-up after exceeding of
internal filter time (if wake-up by LIN or CAN is not disabled by SPI).
