* Filename: Test_dio.c *
* Author: Marco Ziglioli (Doctor Stein) *
* Date: 22/03/2001 *
* Last update: 22/03/2001 *
* 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 *
