java.lang.Object avrora.sim.State.RWIOReg
The RWIOReg
class is an implementation of an IO register that has the simple, default
behavior of being able to read and write just as a general purpose register or byte in SRAM.

method reads the 8-bit value of the IO register as a byte. For simple
RWIOReg
instances, this simply returns the internally stored value.
