Question: An N-bit bidirectional shift register has N parallel data inputs, N outputs, a left serial input (LSI), a right serial input (RSI), a clock input,

An N-bit bidirectional shift register has N parallel data inputs, N outputs, a left serial input (LSI), a right serial input (RSI), a clock input, and the following control signals:
Load: Load the parallel data into the register (load overrides shift).
Rsh: Shift the register right (LSI goes into the left end).
Lsh: Shift the register left (RSI goes into the right end).

(a) If the register is implemented using a 22V10, what is the maximum value of N?
(b) Give equations for the rightmost two cells.
