void CAPSENSE_Init | ( | void | ) |

Capacitive sensing uses two timers: TIMER0 and TIMER1 as well as ACMP. ACMP is set up in cap-sense (oscillator mode). TIMER1 counts the number of pulses generated by ACMP_CAPSENSE. When TIMER0 expires it generates an interrupt. The number of pulses counted by TIMER1 is then stored in channelValues
