3. Draw the block diagram of an 8255 PPI chip and describe its different programming modes. Configure 8255 as follows: port A as output, B as input, and all the bits in port C as output. Determine the content of the Control Register and program the 8255 to get data from port B and send it to both port A and port C. (Assume the standard port addresses of 8255)
