Ashenden P J digital Design an Embedded Systems Approach Using Verilog. Digital Design —Chapter 8 —I/O Interfacing 11. Example: Multiplexed Display. Four BCD inputs, 10MHz clock. Turn on decimal point of leftmost digit only. 50Hz scan cycle (200Hz scan clock) module displaymux ( output reg 3:0 anoden, output 7:0 segmentn, input 3:0 bcd0, bcd1, bcd2, bcd3, input clk, reset ); parameter clkfreq = 10000000; parameter scanclkfreq = 200; parameter clkdivisor =.
