Outputs PWM_H7_1 ... PWM_H7_6
INFO
Measurability of very short pulses
The resolution of the duty cycle at the PWM output is 0.1 %. Due to the limited
edge steepness, very short pulses may not be measured.
■
Example - high frequency pulses:
At 10 kHz output frequency, 0.1 % or 99.9 % duty cycle and low impedance
load, a signal can no longer be measured.
■
Example - low frequency pulses:
1 Hz output frequency allows for a 0.1 % duty cycle to be measured.
