163 hex shift register

163 : hex shift register

How it works

Six 40-bit shift registers. A multiplexer selects input data or recirulating output data.

How to test

on each clock n, six bits are shifted in, and the six bits that were input at clock n-4 are output


# Input Output
0 clk none
1 recirc none
2 data_in[0] data_out[0]
3 data_in[1] data_out[1]
4 data_in[2] data_out[2]
5 data_in[3] data_out[3]
6 data_in[4] data_out[4]
7 data_in[5] data_out[5]
