• 16 bit upcounter • 3-bit prescaler with 8 possible dividing factor (1,2,4,8,16,32,64,128) • Selectable clock – Internal clock sources: LSE, LSI, HSI16 or APB clock – External clock source over ULPTIM input (working with no LP oscillator running, used by Pulse Counter application) • 16 bit ARR autoreload register • 16 bit compare register • Continuous/one shot mode • Selectable software/hardware input trigger • Programmable Digital Glitch filter • Configurable output: Pulse, PWM • Configurable I/O polarity • Encoder mode 特点： the LPTIM is able to keep running whatever the selected power mode the LPTIM can be used as a “Pulse Counter” the LPTIM capability to wake up the system from low-power modes,makes it suitable to realize “Timeout functions” with extremely low power consumption.
