  /** so how this works is from A0 they are getting 5V coz *out is 0x01 with the help
  of K ports first 2 pin i am controlling the Cathode of the led if cathode is 1
  then that led wont glow coz they wont be any pd across the led so to glow the led
  the pin should be 0.
  if ctr is 0x01 --> 0b 00000 0001 -> A8 wont glow A9 will glow
  if ctr is 0x02 --> 0b 00000 0010 -> A8 will glow A9 wont glow
  if ctr is 0x03 --> 0b 00000 0011 -> both wont glow 
  if ctr is 0x00 --> 0b 00000 0000 -> both will glow
