Port S pull device select—Configure pull device polarity on input pin
This bit selects a pullup or a pulldown device if enabled on the associated port input pin.
1 Pulldown device selected
0 Pullup device selected
Port S wired-or mode—Enable open-drain functionality on output pin
This bit configures an output pin as wired-or (open-drain) or push-pull. In wired-or mode a logic “0” is driven
active-low while a logic “1” remains undriven. This allows a multipoint connection of several serial modules. The bit
has no influence on pins used as input.
1 Output buffer operates as open-drain output.
0 Output buffer operates as push-pull output.
