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. 5. ON, if cyclic sense is enabled or during wake-up request. 6. Cyclic activation = pulsed ON during cyclic sense. 7. ON in Fail-Safe mode; if standby mode is entered with active Fail-safe mode the output remains ON in standby mode. Table 45. Status of different functions/features vs operating modes (continued) Function Comments Operating modes Active mode V1-standby static mode (cyclic sense) Vbat-standby static mode (cyclic sense) |
