Port M reduced drive—Select reduced drive for outputs
This register configures the drive strength of Port M output pins 7 through 0 as either full or reduced independent of
the function used on the pins. If a pin is used as input this bit has no effect.
1 Reduced drive selected (approx. 1/5 of the full drive strength).
0 Full drive strength enabled.
Port M pull device enable—Enable pull-up devices on input pins
These bits configure whether a pull device is activated, if the associated pin is used as an input or wired-or output.
This bit has no effect if the pin is used as push-pull output. Out of reset no pull device is enabled.
1 Pull device enabled.
0 Pull device disabled.
