CHAPTER 12 16-BIT INPUT/OUTPUT TIMER
12.5.5 Output compare timing
The output compare is used to issue compare match signals when the free-running
timer and the compare register have matching values, to reverse the output value, and
to generate interrupts. Output reverse timing at the compare match is in sync with the
counter timing.

Interrupt timing
Figure 12.5-8 shows the interrupt timing of output compare.

Change timing of output pin
Figure 12.5-9 shows the change timing of the output pin for output compare.

Note:
To rewrite the compare register, perform within the compare interrupt routine or compare operation
disabled state. Be sure not to occur a compare result match and writing the compare register
simultaneously.
