I'm trying to understand the comparator A+ and Timer capture mode for using honeywell SM351LT sensor. Can't quite seem to bind it together. Sensor is currenlty hooked up with permanent power supply. Comparator output on P1.7 is tied to an led and works pretty much as expected. Furthermore hardware pwm is running on P1.6 with ACLK at 32.768Khz crystal to stay in LPM3. If I put an led on this pin it light up briefly as expected. If I understand correctly the sensor should be powered on CCR0; Read Comparator at CCR1 after minimum 10us. printf reveals indeed 50 cycles between CCR0
