Question:

Assume that the registers in Figure 9-47 are initially [A] = 1011, [B] = 1000, and [C] = 0111. The signals in Figure 9-83 are applied to the register inputs.

(a) Determine the contents of each register at times t₁, t₂, t₃, and t₄.

(b) Describe what would happen if I̅E̅_A were LOW when the third clock pulse occurred.
