(1) Operation of Timer Counters
Figure 5 shows the operation timer counter in complementary PWM mode. Counters TCNT_3 and TCNT_4, which
correspond to channel 3 and channel 4, each count up or down. The initial value of counter TCNT_3 is set to the same
value as the TDDR register, and the initial value of counter TCNT_4 is set to H'0000. Channels 3 and 4 start timer
count operation simultaneously.
