<1> Set each register.
<2> The count operation starts when TCE50 = 1.
<1> PWM output (output from TO50) outputs an inactive level until an overflow occurs.
<2> When an overflow occurs, the active level is output. The active level is output until CR50 matches the
<3> After the CR50 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 TCE50 = 0, PWM output becomes inactive.

For details of timing, see Figures 8-13 and 8-14.
The cycle, active-level width, and duty are as follows.
Clear the port output latch (P50) and port mode register (PM50) to 0.
TCL50: Select the count clock.
