7 title: STMicroelectronics STM32 Low-Power Timers bindings
10   The STM32 Low-Power Timer (LPTIM) is a 16-bit timer that provides several
12    - PWM output (with programmable prescaler, configurable polarity)
13    - Trigger source for STM32 ADC/DAC (LPTIM_OUT)
14    - Several counter modes:
15      - quadrature encoder to detect angular position and direction of rotary
17      - simple counter from IN1 input signal.
