Should we desire to update the duty cycle or period of the above waveform, we would
need to update the COMP1 and COMP2 values using the compare load feature.

6.6.2.17 Usage of the Capture Register
The capture register stores a copy of the counter's value when an input edge (positive,
negative, or both) is detected. After a capture event occurs, no further updating of the
capture register will occur until the SCTRL[IEF] (input edge flag) is cleared by writing a
zero to the SCTRL[IEF].

Resets
6.7.1 General
The TMR module can be reset only by the RST_B signal. This forces all registers to their
reset state and clears the OFLAG signal if it is asserted. The counter will be turned off
until the settings in the control register are changed.
