[Setting]
<1> Set each register.
<2> When TCE5n = 1 is set, the count operation is started.
Note 8-bit timer/event counter 50: P72, PM72
[PWM output operation]
<1> PWM output (output from TO5n) outputs an inactive level after the count operation starts until an overflow
<2> When an overflow occurs, the active level is output.
<3> After CR5n matches the count value, PWM output outputs the inactive level again until an overflow occurs.
<4> Operations <2> and <3> are repeated until the count operation stops.
<5> When the count operation is stopped by setting TCE5n = 0, PWM output becomes the inactive level.
Remark n = 0, 1
• Clear port latches (P72, P73)
• TCL5n: Count clock selection
• CR5n:
• TMC5n: Count operation stop, PWM mode selection, timer output F/F not changed
To stop the count operation, clear TCE5n to 0.
occurs.
The active level is output until CR5n matches the count value of 8-bit timer counter 5n (TM5n).
