Using the Target Control Port
Using the Target Control Port
The Target Control Port is an 8-bit, TTL port that you can use to send
signals to your target system. It does not function like a pattern
generator, but more like a remote control for the target's switches.
Connecting the Target Control
The target control cable is keyed, so it can be inserted only one way.
Plug it into the target control port with the key up and the cable
hanging down.
The lines are color-coded. Bit 0 is brown, bit 1 is red, bit 2 is orange,
and so on up to bit 7 (grey). The black and white lines are both ground.
Pins 0, 2, 4, and 6 are on the top of the connector and arranged in the
same order as the lines.
If you plan on using Open Collector, remember to install pull-up
resistors. The minimum pull-up resistor is 350 Ω and the maximum
sink current into the Target Control Port is 12 mA.
Resetting Your Target System
This example also applies to other types of signals you may want to
send to your target system. The reset line in this case is active low.
Open collector is specified so the line is only pulled low when you
activate the signal.
1. Attach the target control cable to the reset line, using proper termination.
2. Set up a label, RESET.
3. Set the value to 1, for high impedance.
