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
