Design the decoder for the 8253, where A9-A2 =10101011 is used to activate CS. Use NAND and inverters only. Give the port address for each port of this design. Find the control word to program counter 1 for mode 3, binary count, low byte first, followed by high byte. Write a simple program if CLK1 = 1.6 MHz and OUT1 = 1200 Hz. -----References: BARRY B.
