(1) Default option.

(2) Pullup and pulldown resistors: PU = Pullup, PD = Pulldown, PPU = Software-programmable pullup, PPD = Software-programmable pulldown.

(3) This pin should not be pulled up to an always-on voltage domain. Before OTP is loaded, this will be configured as an input, and an active pull-up domain will pull this pin to a high level.
