Fetch part of Fetch-Decode-Execute Cycle: What goes first?
The data held in thememory address is sent along the data bus to the MDR.
The memory address held in the program counter is copied into the MAR
The program counter holds the address of the next instruction to be fetched
The address in the program counter is increased
