When the memory read destination operand is the same as the ALU operation source operand and
the data transfer instruction program is written on the same line as the ALU operation, data loaded
from memory in the memory access stage (MA) cannot be used as the source operand of the ALU
operation instruction. When this occurs, the result of the instruction executed first is used as the
source operand of the ALU operation and is updated as the destination operand of the data load
instruction thereafter. Figure 4.7 is a flowchart of the operation.
