Leave Trigger #1 P & Trigger #2 P wires disconnected

Bench testing Mazda Hall

Test 1.2: Expected resistance between +5v wire and Trigger #2 N wire: 1K

Test 1.3: ground/unground Trigger #1 N wire, should see event counter in triggerinfo go up

PS: technically MAX9926 is not really needed for Hall processing, two channels on the op-amp would do the job just fine and Frankenso has all the jumpers provisioned to make this happen on channels #9 and #11.
