3.4 Clock Source Pads
In addition to the clock signal pads, the frequency sources can also be wired
through the soldering pads. The clock source links to the clock input of the
8254 timer/counter by soldering a wire between its corresponding pads.
For example:
If counter 1 needs a 10kHz clock input, simply solder a wire between pads
"10k" and "CLK1" and insert a jumper in the position "X1" of the JP1 as
shown below:
