(n)
Setting the WRE bit in TWCR to 1 suppresses initial output when synchronous counter clearing
occurs in the Tb interval at the trough in complementary PWM mode and controls abrupt change
in duty cycle at synchronous counter clearing.
Initial output suppression is applicable only when synchronous clearing occurs in the Tb interval
at the trough as indicated by (10) or (11) in figure 11.56. When synchronous clearing occurs
outside that interval, the initial value specified by the OLS bits in TOCR is output. Even in the Tb
interval at the trough, if synchronous clearing occurs in the initial value output period (indicated
by (1) in figure 11.56) immediately after the counters start operation, initial value output is not
suppressed.
