java.lang.Object
  com.github.croesch.micro_debug.mic1.controlstore.MemorySignalSet

public final class MemorySignalSet
extends Object

Represents a set of signals: write, read and fetch.
The signal write determines whether the content of the register MDR should be written to the memory to the address defined by MAR.
The signal read determines whether content of the memory at the address defined by MAR should be written into the register MDR.
The signal read determines whether content of the program memory at the address defined by PC should be written into the register MBR.
