这个程序是拿到2401编写的测试程序，希望可以作为大家的参考！由于水平有限和只是用来自己测试的，程序的结构有点乱，希望大家原谅和大虾的指点。-org 0000 ljmp main org 0013h jmp rx_byte main: powe_up equ p2.0 dataio equ p2.4 clk1 equ p2.3 dr1 equ p3.3 ce equ p2.0

A free-running binary counter circulates through a binary sequence repeatedly. For example, a 4-bit binary counter counts from "0000", "0001 ", . . ., to " 11 1 1" and wraps around.

A 4 bit twisted ring counter is a sequential circuit which produces the following sequence of output values: 0000, 1000, 1100, 1110, 1111, 0111, 0011, 0001 and then repeats. Design a circuit for a 4 bit twisted ring counter that uses four
