The results of this testing/dev are:
Fred.
- PORTA behaviour viewtopic.php?f=9&t=510&p=15743#p15743 - SOLVED!
- Ignition drive circuit viewtopic.php?f=9&t=1188 - SOLVED!
- Opto isolate FTDI+SM viewtopic.php?f=9&t=1231 - SOLVED!
- XGATE bit bang high precision IO viewtopic.php?f=8&t=1070 - Still under development, no rush here, interim solution available.
- Always on power circuit viewtopic.php?f=9&t=903 - Testing by Fred/Dan happening "soon"!

The results of this testing/dev are:
- Able to assign key functions to PORTA pins (last 4 inj channels for 12 cyl, various low speed core IO)
- Able to drive external ignitors reliably and with good spark strength
- Able to use laptop with inverter AND Able to boot into firmware without PNP hack
- Able to assign fuel pins and maybe even move ign pins off timers opening them to speed sensor tasks
