Figure 11.2 shows an example of 50%-duty pulses output with an arbitrary phase difference.
When a compare match occurs while the CCLRA bit in TCSR is set to 1, the OLVLA and
OLVLB bits are inverted by software.

Figure 11.3 shows the FRC increment timing with an internal clock source. Figure 11.4 shows the
increment timing with an external clock source. The pulse width of the external clock signal must
be at least 1.5 system clocks (ø). The counter will not increment correctly if the pulse width is
shorter than 1.5 system clocks (ø).
