Port M pull device select—Determine pull device polarity on input pins
This register selects whether a pull-down or a pull-up device is connected to the pin. If CAN is active a pull-up device
can be activated on the RXCAN[3:0] inputs, but not a pull-down.
1 A pull-down device is connected to the associated Port M pin, if enabled by the associated bit in register PERM
0 A pull-up device is connected to the associated Port M pin, if enabled by the associated bit in register PERM and
Port M 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.
