10. Multifunction Timer Pulse Unit (MTU)
The MTU has three TGRA register input capture/compare-match interrupts, one for each channel,
that can be used as A/D converter activation sources.
10.6 Operation Timing
10.6.1 Input/Output Timing
TCNT Count Timing: Count timing for the TCNT counter with internal clock operation is shown
in figure 10.34. Count timing with external clock operation (normal mode) is shown in figure
10.35, and figure 10.36 shows count timing with external clock operation (phase counting mode).
