* Description: Test PPI82C55MSM on NI DAQ PCI6025E                           *

*----------------------------------------------------------------------------*

* Notes:       Configures port A and port C in input and port B in output    *

*              Test 1:                                                       *

*              Now connect port B to port A and watch on video value changes *

*              in counting order. After connect port B to port C and watch   *

*              the same events on port C                                     *

*              Test 2:                                                       *

*              Connect 8 LEDs on port B and port A and port C lines to Vcc or*

*              GND. Now run this test and watch 8 diode changing in counting *

*              mode and on screen port A and port C values displayed         *
