PWM: minimal and maximal periods and frequencies
In the following formulas you find the minimal/maximal periods and frequen-
cies for the pulse-width modulation (PWM).
PWM: Examples in practice
In this chapter we give you two examples, how to write values in the PWM regis-
ters. All values have to be written in microseconds (μs) in the PWM registers,
therefore remember always the factor 10
-6
s.
