The internal timer/counter 8254 (Counter 0-Counter 2) on the ACL-7120A is
configured as above (figure 3.1). Users can utilize the capabilities of the 8254
through CN5.
CN5 also provides additional wiring to fully use the the 8254. Signal solder
pads are located on the board for use with applications requiring direct
access through these soldering pads (i.e. to circuits on the breadboard area).
The signals of these pads are the same as the signals of CN5. The layout of
signal pads is shown below.
