19 / 184 page  Table 10. Operations in Cyclic Wakeup state Operation Timing mode Functions involved Battery fast OV/UV Always ON Threshold Comparator Battery OV/UV Once ADCV measurements vs. threshold Cells OV/UV Once ADCV measurements vs. threshold GPIO OT/UT Once ADCV measurements vs. threshold OC Monitor Always ON ADCC measurements vs. threshold OT Monitor Always ON ADCT measurements vs. threshold GPO Short Detection Always ON Logical Comparison Clock Monitor Always ON Frequency comparison to secondaty monitor Downward Fault Signalling Always Receivers and Transmitters Cell Open Once ADCV measurements vs. threshold Balancing Open Once Voltage Comparator, Timer Wake up Management Always ON Wake up logic and wakeup sources interfaces ON Cyclic operations have their own periods written by MCU in specific SPI registers. In case the “On-demand” and “cyclic” timing modes are both possible, an “on-demand” command starts a single operation immediately, breaking the cyclic period, and resets the cyclic counter. In GPIO short detection the detection is guaranteed only in the duty phase, if the pin is configured as an output. 4.1.7 Sleep parameters All parameters are tested and guaranteed in the following conditions, unless otherwise noted: 9.6 V < VBAT < 64 V; -40 °C < Tambient < 105 °C Table 11.
