 Status Operation Flow
The flow below illustrates the procedure of detecting count match.
The status register and reset register in the flow correspond to the count match register.
Changing the bit corresponding to the channel from 0 to 1 resets the detection state.
This bit is checked per cycle, Therefore, the values need to be held at least for the period of one cycle.
