# PWM frequency, resolution and duty
# Scope: Ideal timer PWM rate and duty quantization; edge-aligned timer.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

clock = 48000000 Hz
prescaler = 48
periodCounts = 1000
compareCounts = 250

frequency := clock/(prescaler*periodCounts) [Hz]
duty := compareCounts/periodCounts
resolution := 1/periodCounts

check compare within period: compareCounts <= periodCounts

scenario alternative: clock = 3.84e+07 Hz
