Notes

13. SPIVCC is typically connected to the output of buck regulator SW5 and set to 1.800 V

14. Input has internal pull-up to VCOREDIG equivalent to 200 kOhm

15. Input state is latched in first phase of cold start, refer to Serial Interfaces for a description of the PUMS configuration

16. Input state is not latched

17. A weak pull-down represents a nominal internal pull-down of 100 nA unless otherwise noted

18. RESETB, RESETBMCU, SDWNB, SW1PWGD, SW2PWGD have open drain outputs, external pull-ups are required

19. SPIVCC needs to remain enabled for proper detection of WDI High to avoid involuntary shutdown

20. The maximum should never exceed the maximum rating of the pin as given in Pin Connections

21. The weak pull-down on CS is disabled if a VIH is detected at startup to avoid extra consumption in I2C mode

22. The output drive strength is programmable
