Wired-Or Mode register
— Enable open-drain output
This bit configures an output pin as wired-or. If enabled the output is driven active-low only (open drain) while the
active high drive is disabled. This allows a multi-point connection of several serial modules. The bit has no influence
on pins used as inputs.
1 Output buffer operates as open-drain output
0 Output buffer operates as push-pull output
