TDC1000_MCU_STOP

TDC1000_MCU_START

MSP430_TRIGGER

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.
