In the RX, does the same operation with DR only read the register value?

Latest Updated:05/27/2013

Question:

In other product families, reading the output data register (DR) during use of a general input port reads the state of the input pin. In the RX, does the same operation only read the register value?

Answer:

Pin state cannot be read by reading the output data register. The value of the output data register (DR) is read.
Pin state can be read by reading the port register (PORT).
