3.3.5.6
Read: Anytime. Write: Anytime.
The Port S Polarity Select Register selects whether a pull-down or a pull-up device is connected to the pin.
The Port S Polarity Select Register is effective only when the corresponding Data Direction Register bit
is set to 0 (input) and the corresponding Pull Device Enable Register bit is set to 1.
3.3.5.7
Read: Anytime. Write: Anytime.
This register selects whether a port S output is configured as push-pull or wired-or. When a Wired-OR
Mode Register bit is set to 1, the corresponding output pin is driven active low only (open drain) and a
high level is not driven. A Wired-OR Mode Register bit has no effect if the corresponding pin is configured
as an input.
