CHAPTER 12 16-BIT INPUT/OUTPUT TIMER

12.3.2 Operation of 16-bit output compare

16-bit output compare compares the specified compare register value with the 16-bit
free-running timer value, and if they match, it sets an interrupt request flag and
reverses the output level.
I Examples of output waveform
Examples of output waveform are shown below.
❍ Example of output waveform where compare registers 0 and 1 are used
Figure 12.3-3 "Example of output waveform where compare registers 0 and 1 are used (initial
value of output = "0")" shows an example of output waveform where the initial value of output is
specified as "0".
