STOP is connected to TA0.0, as this has quickest
responding ISR. In this way STOP pulses can be
closer together.
START is connected to TA0.1, which is slower.
This produces a delay to timestamp, but this can
be compensated.
TRIGGER is on TA0.2, used to reset counter so
there are no rollover issues.
