Note:
The internal signals shown in Figure 13 are described in Section 10.1.15: Timer signal
descriptions on page 140 and are used throughout the text to describe how the timer
components are interconnected.
10.1 Functional description
The timers can optionally use GPIOs in the PA and PB ports for external inputs or outputs.
As with all STM32W108C8 digital inputs, a GPIO used as a timer input can be shared with
other uses of the same pin. Available timer inputs include an external timer clock, a clock
mask, and four input channels. Any GPIO used as a timer output must be configured as an
alternate output and is controlled only by the timer.
Many of the GPIOs that can be assigned as timer outputs can also be used by another onchip
peripheral such as a serial controller. Use as a timer output takes precedence over
another peripheral function, as long as the channel is configured as an output in the
TIMx_CCMR1 register and is enabled in the TIMx_CCER register.
