7 title: STMicroelectronics STM32 Low-Power Timers
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
