Three of the individual bits of a single microinstruction, which is part of a larger

microprogram, would most likely be used to directly control:

Specify the address of the memory unit into which data should be stored on

the next active clock pulse

Enabling$/$disabling BufferO, Buffer$1,$ and Buffer$2$

Specify the three data values to be stored into Mem$0,$ Mem$1,$ and Mem$2$

Enabling$/$disabling the clock signal from reaching MemO, Mem$1,$ and Mem$2$

Enabling$/$disabling Mem$0,$ Mem$1,$ and Mem$2$
