24 / 91 page  Functional overview STM32L010F4/K4 24/91 DS12323 Rev 3 3.13 Timers and watchdogs The ultra-low-power STM32L010F4/K4 include two general-purpose timers, one low- power timer (LPTIM1), two watchdog timers and the SysTick timer. 3.13.1 General-purpose timers (TIM2, TIM21) Table 5 compares the features of the general-purpose timers. TIM2 This timer is based on 16-bit auto-reload up/down counter. It includes a 16-bit prescaler and four independent channels for input capture/output compare, PWM or one-pulse mode output. TIM2 can work together and be synchronized with the TIM21 timer via the Timer Link feature for synchronization or event chaining. The TIM2 counter can be frozen in debug mode. Any of the general-purpose timers can be used to generate PWM outputs. TIM2 has independent DMA request generation. This timer is capable of handling quadrature (incremental) encoder signals and the digital outputs from 1 to 3 hall-effect sensors. TIM21 This timer is based on a 16-bit auto-reload up/down counter. It includes a 16-bit prescaler and two independent channels for input capture/output compare, PWM or one-pulse mode output. TIM21 can work together and be synchronized with TIM2. TIM21 can also be used as a simple timebase and be clocked by the LSE (32.768 kHz) to provide independent timebase from the main CPU clock. Table 5. Features of general purpose timers Timer Counter resolution Counter type Prescaler factor DMA request generation Capture/compare channels Complementary outputs TIM2 16-bit Up, down, up/down Any integer between 1 and 65536 Yes 4 No TIM21 16-bit Up, down, up/down Any integer between 1 and 65536 No 2 No |
