12.6 Operation Timing
12.6.1 Input/Output Timing
TCNT Count Timing: Count timing for the TCNT counter with internal clock operation is shown
in figure 12.59. Count timing with external clock operation (normal mode) is shown in figure
12.60, and figure 12.61 shows count timing with external clock operation (phase counting mode).
