(o) Counter Clearing by MTU3.TGRA Compare Match
In complementary PWM mode, MTU3.TCNT, MTU4.TCNT, and TCNTSA can be cleared by MTU3.TGRA compare
match when the TWCRA.CCE bit.
Figure 19.69 illustrates an operation example.
Note 1. Use this function only in complementary PWM mode 1 (transfer at crest).
Note 2. Do not specify synchronous clearing by another channel (do not set 1 in the SYNC0 to SYNC4 bits in the timer
synchronous register (TSYRA)).
Note 3. Do not set the PWM duty value to 0000h.
Note 4. Do not set the PSYE bit in timer output control register 1 (TOCR1A) to 1.
