Functional overview (truth table)
Table 4.
1. Supply the processor in low current mode
2. Only active when selected via SPI
3. Input Status can be read by SPI (Status Register 0); Inputs should be configured for static sense (Control
4. Unless disabled by SPI
5. Watchdog is active in V1 standby mode, until I(V1) is below I
6. Activation = ON if cyclic sense is selected
7. Cyclic activation = pulsed ON during cyclic sense
