WOMM[7:0]
Reset
This register configures the output pins as wired-OR. If enabled the output is driven active low only
(open-drain). A logic level of “1” is not driven. It applies also to the CAN outputs and allows a
multipoint connection of several serial modules. This bit has no influence on pins used as inputs.
