By setting a general register as an output compare register, compare match A, B, C, or D can
cause the output at the FTIOA, FTIOB, FTIOC, or FTIOD pin to output 0, output 1, or toggle.
Figure 11.4 shows an example of 0 and 1 output when TCNT operates as a free-running counter, 1
output is selected for compare match A, and 0 output is selected for compare match B. When
signal is already at the selected output level, the signal level does not change at compare match.
Figure 11.5 shows an example of toggle output when TCNT operates as a free-running counter,
and toggle output is selected for both compare match A and B.
