Ignition circuits
Step 24 :
- R14 (1k ohm) located upper right between R22 and R64.
- R64 (1k ohm) located upper right between R14 and BDM.
- R65 (1k ohm) located upper right to the right of U5.
- R15 (470 ohm) located upper right to the right of U5 and above R65.
- JP1 (3 pin 0.100" header strip) for selecting inverted or non-inverted input.
- JP2 (3 pin 0.100" header strip) for selecting inverted or non-inverted output.
- JP7 (wire jumper) Install a wire jumper between these pads for normal operation.
- JP8 (wire jumper) Install a wire jumper between these pads for normal operation.
- U5 (CD74AC86E XOR Gate)
I recommend using an IC socket to install U5 that way if you need to replace the XOR you will be able to without de-soldering/re-soldering.
JP7 and JP8 are there if someone wants to use MCU pins other than Port T2 (JP7) and Port T3 (JP8) with the XOR I/O circuits or to use another output circuit.
The exclusive-OR gate specified in the Bill of Materials is ONLY to be used as logic level outputs to the logic level inputs on EDIS/DIS modules!
