9.3.2 Signal Measurement Modes
The following signal measurement and pulse width modulation modes are provided:
The external signal synchronizes with the internal clock that increments the counter. This
synchronization process can cause the number of clocks measured for the selected signal value to
vary from the actual signal value by plus or minus one counter clock cycle.

NOTE: If INV = 1, counter is clocked on 1-to-0 clock transitions, instead of 0-to-1 transitions.
