Example of Reset-Synchronized PWM Mode: Figure 10.32 shows an example of operation in
reset-synchronized PWM mode. TCNT3 operates as an up-counter in this mode. TCNT4 operates
independently, detached from GRA4 and GRB4. When TCNT3 matches GRA3, TCNT3 is cleared
and resumes counting from H'0000. The PWM outputs toggle at compare match of TCNT3 with
GRB3, GRA4, and GRB4 respectively, and all toggle when the counter is cleared.
For the settings and operation when reset-synchronized PWM mode and buffer mode are both
selected, see section 10.4.8, Buffering.
