Figure 19. Frequency measurement with TIM15 in capture mode
The input capture channel of the Timer 15 can be a GPIO line or an internal clock of the
MCU. The possibilities are the following ones:
• TIM15 Channel1 is connected to the GPIO. Refer to the alternate function mapping in
the device datasheets.
• TIM15 Channel1 is connected to the LSE.
Figure 20. Frequency measurement with TIM16 in capture mode
The input capture channel of the Timer 16 can be a GPIO line or an internal clock of the
MCU.
The possibilities are the following ones:
• TIM16 Channel1 is connected to the GPIO. Refer to the alternate function mapping in
the device datasheets.
• TIM16 Channel1 is connected to the LSI clock.
• TIM16 Channel1 is connected to the LSE clock.
• TIM16 Channel1 is connected to the RTC wakeup interrupt signal. In this case the RTC
interrupt should be enabled.
• TIM16 Channel1 is connected to the HSE/32 clock.
• TIM16 Channel1 is connected to the MCO.
