Port AD general-purpose input/output data—Data Register

When not used with an alternative signal, the associated pin can be used as general-purpose I/O. In

general-purpose output mode the port data register bit value is driven to the pin.

If the associated data direction bit is set to 1, a read returns the value of the port data register bit, otherwise the

buffered pin input state is read if the digital input buffers are enabled

Port AD input data—

A read always returns the buffered input state of the associated pin. It can be used to detect overload or short circuit

conditions on output pins.
