11.3.29 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.

7 CCE 0* R/(W) Compare Match Clear Enable
Specifies whether to clear counters at TGRA_3
compare match in complementary PWM mode.
0: Does not clear counters at TGRA_3 compare match
1: Clears counters at TGRA_3 compare match
[Setting condition]
When 1 is written to CCE after reading CCE = 0
6 to 1 All 0 R Reserved
These bits are always read as 0. The write value should
always be 0.
