This register defines whether the pin is used as an input or an output.
If a peripheral module controls the pin the contents of the data direction register is ignored
3.4.3
If the port is used as an output the register allows the configuration of the drive strength.
3.4.4
This register turns on a pull-up or pull-down device.
It becomes only active if the pin is used as an input or as a wired-or output.
3.4.5
This register selects either a pull-up or pull-down device if enabled.
It becomes only active if the pin is used as an input or wired-or output. A pull-up device can also be
activated if the pin is used as a wired-or output.
3.4.6
This port is associated with the standard Timer.
In all modes, port T pins PT[7:4] can be used for either general-purpose I/O or standard timer I/O.
During reset, port T pins are configured as high-impedance inputs.
