/*
Demo for 8080 (Up counter mode)

Software:
    Compiler: BC++ 3.1
    Compile mode: large
    Project: Up.c
             8080L.Lib
             8000L.Lib

Hardware: I-8000 MCU + 8080

Channel configurations:
    Xor=0 for Low Actived (signal from High to Low ==> change count)
    Low pass filters disabled
    all channel are set to up counter

Wiring:
    Ch0=A0=Up counter
    Ch1=B0=Up counter
    Ch2=A1=Up counter
    Ch3=B1=Up counter
    Ch4=A2=Up counter
    Ch5=B2=Up counter
    Ch6=A3=Up counter
    Ch7=B3=Up counter
