(1) High speed output operation is greater than 5 Khz.
PWM Output Duty Cycle Error
Turn On/Off time for the Micro820 controllers for the PWM output port is
0.2 µs and 2.5 µs max, respectively. Duty cycle error is:
Positive error = 2.5 µs * F
Negative error = -0.2 µs * F
The plot below shows duty cycle error vs. frequency.
To get the duty cycle error at a certain frequency, for example, the user sets
frequency to 20 kHz, and sets duty cycle to 30% in Connected Components
Workbench, then actual duty cycle is
+5%
30%
-0.4%.
