8.7 PWM output function

Function

This function is used to output a variable duty cycle pulse train. The controllable duty

cycle is 0 to 100 % (1 % units).

ON duty 50% 70% 60%

PWM

T T T T = Pulse cycle

The PWM output is enabled when the pulse enable flag is O N. While the pulse enable

flag is ON, the duty cycle (ON duty) can be changed by changing the duty setting value (0

to 100).

The frequency setting is available in the range of 50 to 5000 Hz (1 Hz units) before

turning ON the pulse enable flag. The frequency changing is not allowed while the pulse

enable is ON.

Note that the minimum ON/OFF pulse duration is 100 ms. Therefore, the controllable ON

duty range is limited depending on the frequency setting as follows. If the ON duty setting

value is not available (within 0 to 100), the pulse width error flag comes ON. (PWM output

operation is continued but the duty cycle is not guaranteed)
