(2) Reset-Synchronized PWM Mode Operation
Figure 11.36 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.
