Draw the schematic diagram using CaptureCIS for interfacing the Tri-State Buffer 74LS244 in memory mapped confi guration with AT89C51 microcontroller as per the requirements given below   (a) DIP switches are connected to the 8 input lines of the tri-state buffer through resistors 4.7K. The input line is at logic high when the switch is at open state and at logic low when the switch is at closed state   (b) The output lines of the buffer are connected to the data bus port P0 of the microcontroller   (c) The Port 0 pins are pulled to the supply voltage through 4.7K resistor   (d) The address for the tri-state buffer is assigned as 00F8H. Use logic gates AND, NAND and 3 to 8 decoder IC to decode the address line and generate the address selection pulse for the buffer   (e) The address selection pulse along with the RD\ signal of the microcontroller is used for enabling the buffer   (f) Assume that a regulated supply of 5V is fed to the board from an external ac-dc adaptor. Use a power jack on the board for connecting the external supply. Use fi lter capacitor 0.1MFD/12V along with the jack   (g) Use a crystal frequency of 12MHz for the microcontroller
