(2) Example of Reset-Synchronized PWM Mode Operation
Figure 19.43 shows an example of operation in the reset-synchronized PWM mode.
MTU3.TCNT and MTU4.TCNT operate as up-counters. The counters are cleared when a compare match occurs
between MTU3.TCNT and MTU3.TGRA, and then begin incrementing from 0000h. The output from the PWM pins
toggles every time a compare match occurs in MTU3.TGRB, MTU4.TGRA, and MTU4.TGRB and the counters are
cleared.
