                                     Note:

  SW4 sets the I/O addresses for port1, SW 3 sets the I/O addresses for port
  2, SW2 sets the I/O addresses for port 3, and SW1 sets the I/O addresses for
  port 4. A total of 128 base address settings are available. The switches are
  a binary representation of the decimal memory addresses. SW1-4/1 is the Most
  Significant Bit and switch SW1-4/7 is the Least Significant Bit. The
  switches have the following decimal values:SW1-4/1=1024, SW1-4/2=512,
  SW1-4/3=256, SW1-4/4=128, SW1-4/5=64, SW1-4/6=32, SW1-4/7=16. Turn off the
  switches and add the values of the switches to obtain the correct memory
  address. (On=0, Off=1)

  Note: E4 sets the interrupt to port 1, E3 sets the interrupt to port 2,
  E2 sets the interrupt to port 3, and

  E1 sets the interrupt to port 4.

  Note: To share one interrupt on all four ports it is necessary to
  select the "shared with resistor" setting.

  For 1-3 ports sharing the same interrupt, select the "shared" setting.
