Port H pull device select—Determine pull device polarity on input pins
This register decide if a pull-up or pull-down device if enabled.
1 A pull-down device is connected to the associated Port H pin, if enabled by the associated bit in register PERH
0 A pull-up device is connected to the associated Port H pin, if enabled by the associated bit in register PERH and
Port H wired-or mode—Enable wired-or functionality
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.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.
