Comment
TMODE[3:0] = 1100B selects DEMODULATION mode.
TICONFIG[1:0] = 10B enables interrupt only on Capture events.
CSC = 0 selects the Timer Input from the GPIO pin.
PWMD[2:0] = 000B has no effect.
INPCAP = 0 has no effect.
TEN = 0 disables the timer.
PRES[2:0] = 000B sets prescaler to divide by 1.
TPOLHI,TPOL = 10 enables trigger and Capture on both rising
and falling edges of Timer Input.
TCLKS = 1 enables 32 kHz peripheral clock as timer clock source
