Table 4.
1. Supply the processor in low current mode.
2. Only active when selected via SPI.
3. Unless disabled by SPI.
4. The bus state is internally stored when going to standby mode. A change of bus state leads a wake-up after exceeding of
5. ON in fail-safe condition: If Standby mode is entered with active Fail Safe mode, the output remains ON in Standby mode.
6. Activation = ON if cyclic sense is selected.
7. cyclic activation = pulsed ON during cyclic sense.
