Port S pull device select—Configure pull device polarity on input pin
This bit selects a pull-up or a pull-down device if enabled on the associated port input pin.
1 A pull-down device is selected
0 A pull-up device is 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.
