(1) PWM output basic operation
302
<1> Set each register.
<2> The count operation starts when TCE5n = 1.
Note 8-bit timer/event counter 50: P17, PM17
<1> PWM output (TO5n output) outputs an inactive level until an overflow occurs.
<2> When an overflow occurs, the active level is output. The active level is output until CR5n matches the count
<3> After the CR5n matches the count value, the inactive level is output until an overflow occurs again.
<4> Operations <2> and <3> are repeated until the count operation stops.
<5> When the count operation is stopped with TCE5n = 0, PWM output becomes inactive.

For details of timing, refer to Figures 7-15 and 7-16.
The cycle, active-level width, and duty are as follows.
