first, Design the decoder for the 8253, where A9-A2 =10101011 is used to activate CS.(Use NAND and inverters only. ) Then, from the address determines the port address for each port of this design. Finally, you need to Find the control word to program counter 1 for mode 3, binary count, low byte first, followed by high byte. Use the port numbers and the control words Write a simple program. Assume that CLK1 = 1.6 MHz, after running the program, get the result OUT1 = 1200 Hz.
