Register Description - Virtual Ports
16.7.1
Data Direction
Writing to the Virtual Port registers has the same effect as writing to the regular registers, but allows for
memory-specific instructions, such as bit-manipulation instructions, which are not valid for the extended
I/O memory space where the regular Port registers reside.
