13. SPIVCC is typically connected to the output of buck regulator: SW4 and set to 1.800 V
14. Input has internal pull-up to VCOREDIG equivalent to 200 kOhm
15. Input has internal pull-up to VCORE equivalent to 100 kOhm
16. SPIVCC needs to remain enabled for proper detection of WDI High to avoid involuntary shutdown
17. A weak pull-down represents a nominal internal pull down of 100 nA, unless otherwise noted
18. RESETB & RESETBMCU have open drain outputs, external pull-ups are required
