Port S wired-or mode—Enable wired-or functionality
This register configures the output pins as wired-or independent of the function used on the pins. If enabled the
output is driven active low only (open-drain). A logic level of “1” is not driven.This allows a multipoint connection of
several serial modules. These bits have no influence on pins used as inputs.
1 Output buffers operate as open-drain outputs.
0 Output buffers operate as push-pull outputs.
