* Description: Test STC digital lines (8 lines)                              *

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

* Notes:       Configure DIO 4 5 6 7 in input and DIO 0 1 2 3 in output      *

*              Two way to test this 8 lines:                                 *

*              1) Connect 4 LEDs to output lines and check LEDs lights       *

*                 themselves in counting order. Connect input lines to Vcc   *

*                 or GND and check on video that STC has readed the right    *

*                 nibble                                                     *

*              2) Connect 4 output lines with 4 input lines and check on     *

*                 video that the nibble readed by STC change in counting     *

*                 order                                                      *
