Reset-Synchronized PWM Mode Operation: Figure 9.36 shows an example of operation in the
reset-synchronized PWM mode. TCNT_3 and TCNT_4 operate as upcounters. The counter is
cleared when a TCNT_3 and TGRA_3 compare-match occurs, and then begins incrementing from
H'0000. The PWM output pin output toggles with each occurrence of a TGRB_3, TGRA_4,
TGRB_4 compare-match, and upon counter clears.
