10.3.32 Timer Waveform Control Register (TWCR)
TWCR is an 8-bit readable/writable register that controls the waveform when synchronous counter
clearing occurs in TCNT_3 and TCNT_4 in complementary PWM mode and specifies whether to
clear the counters at TGRA_3 compare match. The CCE bit and WRE bit in TWCR must be
modified only while TCNT stops.
