Me: R0(1),R0(2),R0(3),R0(4) form a register called register_a.

If (Control = 1,1,1)

{

Commutator_a = chosen.

}

else if (Control = 0,1,1)

{

Commutator_b = chosen.

}

else if (Contol = 0, 0,0)

{

commutator_c = chosen;

}

else if (Control = 0,0,1)

{

No commutator is chosen; // the status is mask - interrupt.

}
