Reduced Drive Port T — This register configures the drive strength of each port T output pin as either full or
reduced. If the port is used as input this bit is ignored.
0 Full drive strength at output.
1 Associated pin drives at about 1/3 of the full drive strength.
Pull Device Enable — This register configures whether a pull-up or a pull-down device is activated, if the port
is used as input. This bit has no effect if the port is used as output. Out of reset no pull device is enabled.
0 Pull-up or pull-down device is disabled.
1 Either a pull-up or pull-down device is enabled.
