M2_1E is a 2-to-1 multiplexer with enable. When the enable input (E) is High, the M2_1E chooses one data bit from two sources (D1 or D0) under the control of select input (S0). When E is High, the output (O) reflects the state of the selected input. When Low, S0 selects D0 and when High, S0 selects D1. When E is Low, the output is Low.
